Male Sexual Desire: An Overview of Biological, Psychological, Sexual, Relational, and Cultural Factors Influencing Desire

Sexual desire and erotic fantasies questionnaire: development and validation of the sexual desire scale (SDEF1)

The evolution in conceptualization of sexual desire has stimulated many attempts to measure it. However measures able to assess multiple expressions of desire in all sexual identities are still lacking. The main aim of the present study was to test the psychometric properties of the Sexual Desire and Erotic Fantasies questionnaire - Part 1 Sexual Desire (SDEF1), developed as a sex-positive measure of different sexual desire expressions. The SDEF1 was assessed in 1773 participants from the Italian general population (1105 women, 645 men, and 23 other genders; ranged between 18-78 years old, mean age 29.31 ± 10.35) on an online survey, together with the Sexual Desire Inventory - 2, the International Index of Erectile Function, the Female Sexual Function Index, and the Marlowe-Crowne Social Desirability Scale-Short Form. Results support a factorial structure of six dimensions, including 28 items and accounting for 58.11% of the total variance: sexual desire, negative feelings to sexual desire, autoerotic desire, regular partner desire, attractive person desire, and responsive desire. The confirmatory factorial analysis showed satisfactory indexes (RMSEA = 0.042 [90% CI = 0.039-0.045]; GFI = 0.97; NFI = .96; and CFI = 0.97). Regression coefficients ranged from 0.39 to 0.94 and were all statistically significant (p < 0.001). The SDEF1 showed good psychometric properties such as internal reliability, construct, and discriminant validity, and to differentiate women and men with and without sexual difficulties. Men reported significantly higher levels of desire than women in all areas except for desire for a regular partner, were no gender difference was detected. Desire for autoerotic activity was the factor accounting for more variance explained among genders (11.7%). The SDEF1 could be a useful measure to assess different areas of sexual desire and its use could be recommended for clinical and research purposes.

Understanding the Ebbs and Flows of Sexual Desire: A Daily Diary Study on the Temporal Associations Between Dyadic Sexual Desire and Partner Interactions

Sexual desire has often been conceptualized and studied as an individual trait. However, empirical evidence suggests that there is also value in studying it as a state and dyadic construct. Through a daily diary study with a randomized controlled experimental design, we aimed to explore (i) how the roles that partners fulfill in dyadic interactions are associated with daily fluctuations in dyadic sexual desire, (ii) whether these roles can be leveraged to affect sexual desire for one's partner, and (iii) whether effects of partner interactions on dyadic sexual desire vary by gender. In total, 163 mixed-gender couples (N = 326), with a mean age of 30.3 years (SD = 7.95), participated. During 22 consecutive days, participants reported daily on their dyadic sexual desire, as well as on several aspects of their interactions. Couples in the experimental condition additionally received assignments that manipulated their partner interactions. Analyzing our data using Multilevel Modelling techniques for longitudinal dyadic data, we found that daily dyadic sexual desire was associated with what each partner takes, gives, and receives in relation with their affiliation, sexuality and exploration needs. Additionally, women's sexual desire was associated with what their partner reported taking, giving, and receiving during affiliative interactions, and with perceived but not enacted responsiveness to their sexuality and exploration needs. Our results suggest that daily ebbs and flows of sexual desire may be partly explained by temporal changes in interactions between partners, making them possible valuable targets for clinical interventions.

Sexual functioning after penile cancer surgery: comparison between surgical approaches in a large patient cohort

Very few studies examine sexuality after penile cancer (PeCa) surgery and/or evaluate predictors of sexual satisfaction. Since 2016, primary PeCa patients at our institute routinely received the International Index of Erectile Function (IIEF-15) questionnaire: preoperatively (baseline) and 3-, 6-, 12- and 24-months postoperatively. We included patients who were surgically treated at our institute and completed the baseline and ≥1 follow-up questionnaire. Sexually active patients were divided into groups: wide local excision (WLE), glansectomy, partial penectomy and total penectomy with perineal urethrostomy. Linear mixed effects models were used for longitudinal analyses with repeated measures to examine predictors of overall sexual satisfaction. 647 patients with (suspected) PeCa were evaluated and received questionnaires. 543 (83.9%) returned the questionnaires. 242 were suitable for analysis. Preoperatively, only 55/242 (22.7%) were sexually active. Postoperatively, the number of sexually active patients increased for WLE (30.8% at baseline, 43.5% at two-year follow-up) and glansectomy (35.0% to 40.0%, both p < 0.001). Sexual satisfaction was below the level of healthy men in all patients, both pre- and postoperatively. Longer follow-up time, younger age, and penile-sparing surgeries were predictors for better sexual satisfaction. Our findings underscore the importance of considering penile-sparing surgical approaches in the treatment of PeCa when oncologically feasible. The significant improvements in sexual activity and sexual satisfaction following WLE and glansectomy support this approach. However, the overall sexual satisfaction after all PeCa surgery remains below the level of the healthy men, both pre- and post-operative, emphasizing the importance of guidance throughout the treatment trajectory.

Prevalence of masturbation and masturbation guilt and associations with partnered sex among married heterosexual Chinese males in an outpatient clinical setting: a retrospective single center study

BACKGROUND

Solo masturbation is not an activity performed exclusively in single males but can also occur among married males, and is often associated with feelings of guilt. This study aimed to explore the prevalence of solo masturbation and associated masturbation guilt and the possible associated factors, including age, residence type (rural or urban), duration of marriage, parental status, income level, education level, body mass index, current smoking and drinking status, anxiety and depression status and their possible associations with the frequency of partnered sex among married heterosexual Chinese males.

MATERIALS AND METHODS

A series of males attending our outpatient clinic were included and analyzed in the study. Approximately 71.2% (334/469) of these males had engaged in masturbation during the studying period, whereas 76.6% (256/334) of those who reported engaging in masturbation reported at least some sense of guilt.

RESULTS

Masturbation frequency was weakly positively associated with young age (OR 1.11) and education level (OR 1.24), whereas weak positive correlations were found between masturbation guilt and young age, anxiety and depression level (ORs ranged from 1.08 to 1.30). In addition, we found that the frequency of partnered sex was weakly positively associated with a masturbation frequency of less than once a month (adjusted OR 1.50) and once a month (adjusted OR 1.35). A weak positive correlation was observed between the frequency of partnered sex and a little sense of guilt (adjusted OR 1.60). In contrast, a weak negative association was observed between the frequency of partnered sex and a very big sense of guilt, with an adjusted OR of 1.67.

CONCLUSIONS

In summary, in married heterosexual Chinese males, masturbation along with its associated guilt is a relatively frequent phenomenon. We obtained evidence supporting both compensatory and complementary relationships between masturbation, masturbation guilt and the frequency of partnered sex. Masturbation and its related guilt should receive more attention in clinical practice, given its high prevalence and possible relationship with partnered sex and couple relationships.

Exploring sexual desire and fantasies: a cross-sectional online study on gender differences on Iranian adults

Background Sexual fantasies represent a cognitive pattern that influences sexual activation and desire. This study aims to investigate the relationship between sexual fantasies, sexual desire and overall sexual functioning among Iranian adults. Methods A total of 1353 volunteers from the general population participated by filling out questionnaires including, the Sexual Desire and Erotic Fantasies Questionnaire, the International Index of Erectile Function and the Female Sexual Function Index. Sexual fantasies were categorized based on predefined criteria. Statistical analyses were conducted using correlation and regression techniques to explore these relationships. Results Men reported more explicit sexual fantasies, including active roles, common sexual behaviours and dominance, during sexual activities (mean1.62, s.d.1.16), taboo elements (e.g. sex with minors, animals, family members and rape; mean0.38, s.d.0.60) and fantasies with diverse partners (mean5.18, s.d.4.16). In contrast, women preferred romantic content (mean1.97, s.d.0.97) and a passive role. No gender differences were observed in bondage, dominance, sadism and masochism fantasies. Both genders showed a strong correlation between sexual fantasies and sexual desire (Men0.461, Women0.372). Conclusion Understanding these patterns in a conservative country, such as Iran, may contribute to culturally sensitive intervention in traditional culture. For instance, in sex therapy or workshops for couples on utilizing fantasy to enhance sexual satisfaction, subject to the values of modesty and privacy. This research reveals valuable insight into sexual imagery and sexual performance, and fills a gap in cultural studies. However, further research is needed to validate these findings.

Development and validation of the sexual distress scale: results from a collectivistic culture

BACKGROUND

Literature lacks a comprehensive measure of sexual distress that could be applied to both clinical and non-clinical populations, regardless of the gender and relational status of the respondents. The current study, therefore, developed and validated Sexual Distress Scale (SDS).

METHOD

The development and validation of the SDS involved two consecutive studies with a total of 656 participants (men = 300, women = 356; Mage=22 years) from Pakistan. The studies included exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and assessments of convergent and divergent validity.

RESULTS

The SDS demonstrated high reliability in both the studies (α = 0.911 & 0.946). Item-total correlations ranged from 0.670 to 0.878 (p < 0.01). EFA revealed a single-factor structure consisting of 8 items. CFA confirmed this structure, projecting a good comparative fit index (CFI = 0.913). The scale's convergent validity was established through significant positive correlations with depression (r = 0.845, p < 0.01), anxiety (r = 0.847, p < 0.01), and stress (r = 0.786, p < 0.01). Divergent validity was established through significant inverse correlations with life satisfaction (r = -0.972, p < 0.01) and emotional expressivity (r= -0.935, p < 0.01). Compared to women, men experienced significantly higher levels of sexual distress (p < 0.01; Cohen's d = 0.448).

CONCLUSION

The study bridges a substantial knowledge gap in the measurement of sexual distress. The findings highlight the impact of sexual distress on psychosocial health. The study opens avenues for further research and targeted interventions in sexuality, especially within the collectivistic cultures.

Desire discrepancy in long-term relationships: A qualitative study with diverse couples

Sexual desire discrepancy is one of the most common, and potentially distressing, aspects of couples' sexual health. There are gaps in the literature exploring desire discrepancy specifically in distressed couples, as well as in queer (sexual and/or gender minority) couples. This study sought to gather qualitative data regarding long-term couples' experiences with distressing desire discrepancy. Semi-structured interviews were conducted with both heterosexual and queer partners of varying gender identities (n = 26) to fill these research gaps. Interviews included couple interviews, as well as individual interviews with partners. Data analysis was conducted with thematic analysis, which yielded four primary themes across the course of relationships: Sexual and relationship satisfaction; Changes in sexual frequency, desire, and behavior; Changes in barriers to sex; and Coping with desire discrepancy. Findings can inform clinical interventions focused on desire discrepancy, as well as future research investigating couple's sexual health.

Nutritional aphrodisiacs: Biochemistry and Pharmacology

In 2022, the global prevalence of erectile dysfunction (ED) was estimated to be at least 150 million cases. This number is greatly suspected to be underestimate as most men withhold information about ED. Also, about 15% of world population have infertility troubles, and male factors are responsible for almost half of these cases. Studies have shown that the quality of semen has decreased in the past several decades owing to various health factors and environmental toxicants. The current medical interventions involve the inhibition of phosphodiesterase 5 which suffer from serious side effects and costly. One of the popular and most sought interventions are the natural and nutritional remedies as they are foods in essence and potentially with no harm to the body. Therefore, the goal of this paper is to provide a review of the most common nutritional aphrodisiacs with increasing libido and fertility highlighting the potential active constituents as well as the underlying mechanisms.

Male delayed orgasm and anorgasmia: a practical guide for sexual medicine providers

Delayed orgasm (DO) is defined as increased latency of orgasm despite adequate sexual stimulation and desire. Anorgasmia (AO) is characterized as the absence of orgasm. Etiologies of DO/AO include medication-induced, psychogenic, endocrine, and genitopelvic dysesthesia. Given the multifactorial complex nature of this disorder, a thorough history and physical examination represent the most critical components of patient evaluation in the clinical setting. Treating DO/AO can be challenging due to the lack of standardized FDA-approved pharmacotherapies. There is no standardized treatment plan for DO/AO, though common treatments plans are often multidisciplinary and may include adjustment of offending medications and sex therapy. In this review, we summarize the etiology, diagnosis, and treatment of DO/AO.

The Nuances of Intimacy: Asexual Perspectives and Experiences with Dating and Relationships

Asexuality studies are an emerging field in North America and Europe which lack large-scale, qualitative studies. Much existing research focuses on defining and categorizing asexuality, with researchers calling for more focus on the romantic and sexual relationships of asexual people. Drawing from an online survey with 349 participants, this paper describes the perceptions and experiences that asexual people have with dating and relationships. Participants answered 16 open-ended and 9 close-ended questions. After rounds of coding, three themes were selected for examination. These were dating, romantic and/or sexual relationships, and platonic relationships. These results showcase the challenges asexuals face with dating while also demonstrating how asexual people actively dismantle understandings of romantic, sexual, and platonic relationships through their own experiences and perspectives. Overall, this study provides greater legitimacy to the fluidity of asexuality and asexual relationships.

Quality of life and sexuality with penile prosthesis: a systematic review and pooled analysis

INTRODUCTION

Quality of Life and Sexuality with Penile Prosthesis (QoLSPP) is the first validated questionnaire to specifically evaluate the satisfaction of patients undergoing penile prosthesis implantation. Our primary aim was to conduct a systematic review and pooled analysis of articles reporting QoLSPP.

EVIDENCE ACQUISITION

A comprehensive bibliographic search on the MEDLINE, Scopus, Web of Science, and Cochrane Library databases was performed in April 2023. Studies were selected if they assessed male subjects (P) undergoing penile prosthesis implantation (I) with or without comparison with other treatments (C), reporting the patient satisfaction according to QoLSPP (O). Prospective and retrospective original studies were included (S). The risk of bias was assessed using the ROBINS-I tool and the Knoll method. Means and standard deviations (SDs) of QoLSPP scores were included in the pooled analysis. PROSPERO ID: "CRD42023427261."

EVIDENCE SYNTHESIS

A total of 10 studies investigating 1105 patients were included in the systematic review; of these, eight articles describing the outcomes of 693 subjects were eligible for the pooled analysis. Overall serious risk of bias was found in 2/3 of nonrandomized comparative studies (66%), while seven single-arm studies (100%) were classified as having a high risk of bias. Pooled analysis of the QoLSPP-Functional domain revealed an overall effect size (ES) of 4.22 points (95% CI 4.04-4.40; P<0.001). The QoLSPP-Relational pooled score was 4.17 points (95% CI 4.03-4.31; P<0.001). The QoLSPP-Social pooled score corresponded to 4.21 points (95% CI 4.02-4.40; P<0.001). Pooled analysis of the QoLSPP-Personal domain showed an overall ES of 3.97 points (95% CI 3.61-4.32; P<0.001). There was insufficient data to pool QoLSPP total scores.

CONCLUSIONS

Patients undergoing penile prosthesis implantation report positive scores in all QoLSPP domains, demonstrating high satisfaction levels. Future studies are needed to improve the evidence on the topic.

Deepening Sexual Desire and Erotic Fantasies Research in the ACE Spectrum: Comparing the Experiences of Asexual, Demisexual, Gray-Asexual, and Questioning People

Over the past 30 years, an increasing number of people have identified within the asexual (ACE) spectrum recognizing an absence/low/situational sexual attraction to individuals of any gender. The current study aims to deepen the knowledge of sexual desire, erotic fantasies, and related emotions within the ACE spectrum. A total of 1072 Italian volunteers were recruited to take part to the present study via social media. Data were collected from October 2021 to January 2022 using the Sexual Desire and Erotic Fantasies questionnaire and the Sexual Desire Inventory-2. Participants were divided into four groups: asexual, demisexual, gray-asexual, and questioning. Focusing on sexual desire, asexual people reported significantly lower scores than the other groups in all the dimensions except for "negative feelings to sexual desire," while demisexual participants showed the higher scores in all the domains except for "negative feelings to sexual desire." The questioning group reported the highest scores in the "negative feelings toward sexual desire" compared to the asexual and demisexual ones. The asexual group reported significantly lower scores than the other groups in fantasies frequency, fantasies importance, negative emotions, and sharing and experiencing. The demisexual group showed higher frequency of romantic fantasies than the asexual and gray-asexual ones. The results showed some specific patterns of desire and fantasies among the asexual, gray-asexual, demisexual, and questioning groups. These data may provide relevant material to clinicians working with asexual patients who need greater awareness about the diversity and heterogeneity of the sexual experience within the ACE spectrum.

Rights or Obligations: The Extent to Which Sexual Desire and Gender Roles Determine Sexual Intimacy in Romantic Relationships

The present study aims to investigate the relationship between traditional gender roles and the frequency of sexual intimacy within romantic relationships, considering sexual desire and societal norms and expectations. The study was conducted among a convenience sample of men and women in Israel. The survey included measures of sociodemographic information, traditional gender roles, sexual desire, perceived partner's sexual desire, and frequency of engaging in sex. Findings suggest that men who embraced less traditional gender roles exhibit a greater synchronization between their own sexual desire and their perceived partner's sexual desire, whereas women who embraced more traditional gender roles tend to rely more on their partners' sexual desire in their frequency of sex. These results imply that men's sexual desire plays a significant role in determining the frequency of sexual activity in romantic relationships, especially in relationships where traditional gender roles are more strongly embraced. Findings from the current study underscore the idea that the decision to engage in intimate acts may not solely hinge on individual sexual desire; rather, it operates within a broader context influenced by societal and cultural expectations. It is important to challenge societal norms to promote more balanced and equitable sexual dynamics in committed relationships.

The Role of Dyadic Sexual Desire Similarity in Predicting Sexual Behaviors in Cohabitating Couples: An Ecological Momentary Assessment Study

Although researchers are increasingly paying attention to the dyadic nature of sexual desire and its relevance to sexual and relational outcomes, our understanding of how sexual desire operates on a couple level and how it may influence the occurrence of sexual activity in relationships remains limited. This study used ecological momentary assessments to explore to what extent similarity in levels of desire for sex with one's sexual partner, or dyadic sexual desire, was associated with sexual initiations, receptivity to one's partner's initiations, and partnered sexual activity, and how these associations were moderated by perceived partner support. Ninety-four cohabitating couples (M age = 26.30, SD = 7.60) provided six reports a day for 10 consecutive days. We used response surface analysis to examine the associations among both the degree and direction of (dis)similarity in partners' dyadic desire and each of the three outcome variables. Our results revealed that although partners tended to experience similar levels of desire on a moment-to-moment basis, similarity in desire levels was not associated with the three outcome variables. Rather, higher desire within couples predicted each partner's behavioral outcomes. At lower levels of perceived partner support, dyadic sexual desire was negatively associated with women's receptivity to sexual initiations by their partners, indicating high context-sensitivity of women's sexual responding. These findings offer new insights into the links between the similarity in partners' levels of dyadic desire and sexual behaviors in couples, suggesting the need for increased focus on maintaining desire and promoting perceived partner support in clinical practice.

Romantic Attachment and Sexual Desire: The Role of Desire Target

Attachment insecurities are characterized by distinct approaches to intimacy and sex, yet their roles in sexual desire remain largely unexamined. Drawing from theories of attachment and behavioral motivation, the current study investigated the role of attachment insecurities in sexual desire and how that role differs by desire target. The Sexual Desire Inventory provided both a general dyadic desire measure and a measure differentiating between partner-specific desire and desire for an attractive potential sexual partner (attractive other desire). In a sample of 321 young adults (51% men), two structural equation models (SEMs) were compared, each with attachment predicting desire: a Dyadic Combined model and a Partner Type model. Models accounted for gender, relationship status, sexual identity, racial/ethnic identity, number of previous sexual partners, and measurement error. Preliminary confirmatory factor analyses indicated adequate factor loadings (>.40) for both desire measures, yet superior fit for the partner type measure. In the SEMs, the Partner Type model outperformed the Dyadic Combined model across all indices. Attachment avoidance predicted lower partner-specific desire, yet higher attractive other desire. Attachment anxiety predicted higher partner-specific desire, yet was unrelated to attractive other desire. Findings suggest the discomfort with intimacy characterized by attachment avoidance deters interest in sex with romantic partners, yet may enhance sexual interest in nonattachment figures. Several discrepant associations across desire measures indicate that distinguishing between desire targets is critical for fully understanding individual differences in desire. Partner-specific sexual desire may be a unique experience that should not be conflated with other forms of sexual desire.

Characteristics of Young People Reporting a Low Sexual Desire in Switzerland

This study explores the characteristics of young female and male adults (mean age 26.3 years) reporting a low sexual desire. A 2017 Swiss national survey was carried out among young adults. Participants were divided into two groups based on their level of sexual desire: Low and High. Overall, 17.2% of females and 5.7% of males reported a low sexual desire. At the multivariate level, compared to females in the High group, females in the Low group had higher odds of being dissatisfied with their social life and with their sexual life in the past 4 weeks, having no current relationship and having accepted several times sexual intercourse without really wanting. Compared to males in the High group, males in the Low group had higher odds of reporting a non-heterosexual attraction (trend), having no current relationship and having accepted several times sexual intercourse without really wanting. The prevailing idea that young people, particularly males, always have high levels of sexual desire may not be accurate and warrants further consideration. These results show that sexual desire encompasses social aspects and underscore importance of addressing how stereotypes and social norms may influence our sexuality.

Sexual Desire and Erotic Fantasies Questionnaire: The Development and Validation of the Erotic Fantasy Use Scale (SDEF2) on Experience, Attitudes, and Sharing Issues

BACKGROUND

The investigation of sexual fantasies is a delicate issue within sex research. Most studies have focused on the content of these fantasies, rather than on use, experiences, attitudes, and sharing issues, which are fundamental aspects within sexual therapy. The main aim of the present study was to develop and validate the "Sexual Desire and Erotic Fantasies questionnaire-Part 2. Use of Erotic Fantasies (SDEF2)".

METHODS

The SDEF2 was completed by 1773 Italian participants (1105 women, 645 men, and 23 other genders).

RESULTS

The final 21-item version presented a five-factor structure (fantasies frequency, fantasies normality, fantasies importance, negative emotions, and sharing and experiencing). The SDEF2 showed good psychometric properties, internal reliability, construct, and discriminant validity, appearing to be able to differentiate between sexually clinical and functional women and men (based on the FSFI and IIEF cut-off scores).

CONCLUSIONS

The possibility of assessing fantasies frequency, attitudes, and emotions may be extremely useful both for research and clinical purposes. The current study seems to validate that the SDEF2 is a useful measure of assessing the different aspects related to a fantasizing activity, which was shown to be associated with sexual functioning and satisfaction.

Sexual Satisfaction Mediates the Effects of the Quality of Dyadic Sexual Communication on the Degree of Perceived Sexual Desire Discrepancy

Difficulties related to sexual desire discrepancy are among the most common complaints in people seeking help in therapy. The aims of the current study were to test a mediation model using a bootstrapping procedure where the quality of the dyadic sexual communication plays a key role in increasing or diminishing the degree of perceived sexual desire discrepancy through sexual satisfaction. An online survey was administered through social media to N = 369 participants involved in a romantic relationship, measuring the quality of dyadic sexual communication, sexual satisfaction, the degree of the perceived sexual desire discrepancy, and a series of relevant covariates. As expected, the mediation model showed that a better quality of dyadic sexual communication is related to a lower degree of perceived sexual desire discrepancy through increased sexual satisfaction (β = -0.17, SE = 0.05, [95% CI = -0.27, -0.07]). The effect held over and above the effect of the relevant covariates. The theoretical and practical implications of the present study are discussed.

Opioid-Induced Sexual Dysfunction in Cancer Patients

Simple Summary

Sexual disorders affect up to 80% of cancer patients, depending on the type of cancer, yet they are commonly overlooked and untreated. Opioid-induced sexual dysfunction (OISD) is reported in half of opioid users. The pathophysiology of OISD—still a subject for research—may include disorders of both the endocrine and nervous systems, expressed in, among other things, erectile dysfunction and declined sexual desire, sexual arousal, orgasm, and general satisfaction with one’s sex life. The etiology of sexual dysfunction in cancer patients is usually multifactorial, so the management should be multifaceted and individualized by targeting pathophysiological factors. The treatment options for OISD are few and include testosterone replacement therapy, bupropion, opioid antagonists, phosphodiesterase type 5 inhibitors, plant-derived substances, and non-pharmacological treatments, although the evidence is insufficient. One of the treatment options may also be a choice of an opioid that is less likely to cause sexual dysfunction, yet further research is necessary.

Abstract

Sexual dysfunction is common in patients with advanced cancer, although it is frequently belittled, and thus consistently underdiagnosed and untreated. Opioid analgesics remain fundamental and are widely used in cancer pain treatment. However, they affect sexual functions primarily due to their action on the hypothalamus–pituitary–gonadal axis. Other mechanisms such as the impact on the central and peripheral nervous systems are also possible. The opioid-induced sexual dysfunction includes erectile dysfunction, lack of desire and arousal, orgasmic disorder, and lowered overall sexual satisfaction. Around half of the individuals taking opioids chronically may be affected by sexual dysfunction. The relative risk of sexual dysfunction in patients on chronic opioid therapy and opioid addicts increased two-fold in a large meta-analysis. Opioids differ in their potential to induce sexual dysfunctions. Partial agonists and short-acting opioids may likely cause sexual dysfunction to a lesser extent. Few pharmaceutical therapies proved effective: testosterone replacement therapy, PDE5 inhibitors, bupropion, trazodone, opioid antagonists, and plant-derived medicines such as Rosa damascena and ginseng. Non-pharmacological options, such as psychosexual or physical therapies, should also be considered. However, the evidence is scarce and projected primarily from non-cancer populations, including opioid addicts. Further research is necessary to explore the problem of sexuality in cancer patients and the role of opioids in inducing sexual dysfunction.

Perceived Changes in Sexual Interest and Distress About Discrepant Sexual Interest During the First Phase of COVID-19 Pandemic: A Multi-Country Assessment in Cohabiting Partnered Individuals

Due to COVID-19 pandemic, different restrictive measures in terms of physical distancing and lockdowns have been introduced in most European countries, affecting all facets of social life. Currently, little is known about how partnered individuals perceive changes in their sexual life during this complex emergency. This study explored retrospectively assessed changes in sexual interest for one's partner and levels of distress related to perceived sexual interest discrepancy during the first phase of the pandemic in a large-scale online sample of partnered individuals (n = 4813; Mage = 38.5 years, SD = 10.74) recruited between May and July 2020 in seven European Union countries and Turkey. We also examined the possible role of approach/avoidance motives for sex in reported changes in sexual interest and associated distress. Most participants (53%) reported no change in their sexual interest during the pandemic, followed by those who reported an increase (28.5%). The pattern was similar across the eight countries. Distress about discrepant sexual interest, which was only weakly related to changes in sexual interest, was significantly associated with relationship quality and emotional closeness with a partner, coping with and worrying about the pandemic, and specific motivation for sex. In contrast to avoidant and relationship-focused approach motivation, ego-focused approach motivation was related to stable sexual interest during the pandemic. The current study contributes to the understanding of the link between sexual interest and complex emergencies. Considering that the COVID-19 pandemic continues, the reported experiences and perceptions are prone to change.

Associations between Fluctuating Shame, Self-Esteem, and Sexual Desire: Comparing Frequent Porn Users and a General Population Sample

In the present study, we explore the proposed cyclic models for problematic hypersexuality (PH) that involve shame, self-esteem, and sexual desire. These cyclic models are characterized by temporal associations but have not been investigated previously with intensive longitudinal designs. In this study, we collected up to 70 measurements per participant within a period of seven consecutive days, which allowed us to investigate associations between fluctuations of shame, self-esteem, and sexual desire. Participants were divided in four subgroups: (1) women (n = 87); (2) men (n = 46) from a general population convenience sample; (3) men watching porn >2 times per week, showing non-problematic hypersexuality (NH; n = 10); and (4) men watching porn >2 times per week, experiencing PH (n = 11). Multilevel analyses, including cross-level interactions, were used to investigate between-group differences in intraindividual processes. Results showed that prior increases in shame forecasted higher current sexual desire for men with PH, but not for the other groups, suggesting that men with PH use sexual desire to downregulate dysphoric feelings of shame. Differences between groups in associations between self-esteem and sexual desire were also found. Based on our results, we propose the Split Pleasure/Shame model, which represents emotion dysregulation in PH, and juxtapose this with the pleasurable experience of sex by non-PH groups. Further intensive longitudinal research is necessary to test this model and, more generally, to investigate the fluctuating nature of sexual desire.

Sex in Chemsex: Sexual Response, Motivations, and Sober Sex in a Group of Italian Men Who Have Sex With Men With Sexualized Drug Use

BACKGROUND

Most studies on chemsex focus on the health risks associated with the practice, whereas less attention has been paid to the perception of sexual gratification in men who have sex with men (MSM) who use these substances.

AIM

The purpose of this study was to explore the effects of chemsex substances on sexual response, motivations to engage in chemsex and the relationship with sober sex.

METHODS

Thirty-one Italian cisgender MSM involved in sexualized drug use were interviewed and transcripts were thematically analyzed.

OUTCOMES

An ad hoc grid exploring sociodemographic data, chemsex sexual experience, motives, and relationships with sober sex was used during telephone-based interviews.

RESULTS

Participants showed significant individual differences in how chems may affect their sexual experience. The most reported effects were an increase in sexual desire and subjective arousal, access to higher disinhibition, possible erection and ejaculation difficulties, significant extension of the sexual experience duration, and an intensified perception of intimacy and pleasure. All the positive outcomes of substances on sex creates a great curiosity around chemsex, which is among the primary motives to engage in chemsex for the first time. Over time, other motives may emerge, also connected to substance abuse and craving. Some men reported to be motivated by their partners and friends and to use chemsex to cope with depressive mood/anxiety symptoms, stress and sexual problems. Many differences were reported between chemsex and sober sex. Chemsex seems to embody the idea of transgressive and exciting sex, while sober sex is outlined as a more intimate encounter, that can be significantly affected by performance anxiety.

CLINICAL TRANSLATION

These results offer some new perspectives that may add interesting information to the literature and be fundamental for future prevention and harm-reduction projects.

STRENGTHS & LIMITATIONS

Although this study is based on a small group of Italian MSM and the interviews were not audio-recorded, transcripts were consistent with scientific literature that considers it important to pay attention to the positive links between sex and substance use.

CONCLUSION

The promotion of safer sexual behavior should contemplate an in-depth discussion and recognition of both pleasurable and distressing aspects of chemsex sexual experience, its motivations over time and perceived differences with sober sex.

Evaluation of the in Vivo Aphrodisiac Activity of a Cyclotide Extract from Hybanthus enneaspermus

Hybanthus enneaspermus is an Indian folk medicinal herb that has been widely used as a libido enhancer. This plant belongs to the Violaceae plant family, which ubiquitously contains disulfide-rich cyclic peptides named cyclotides. Cyclotides are an expanding plant-derived peptide family with numerous interesting bioactivities, and their unusual stability against proteolysis has attracted much attention in drug design applications. Recently, H. enneaspermus has been reported to be a rich source of cyclotides, and hence, it was of interest to investigate whether cyclotides contribute to its aphrodisiac activity. In this study, we evaluated the in vivo aphrodisiac activity of the herbal powder, extract, and the most abundant cyclotide, hyen D, extracted from H. enneaspermus on rats in a single dose regimen. After dosing, the sexual behaviors of male rats were observed, recorded, analyzed, and compared with those of the vehicle group. The results show that the extract and hyen D significantly decreased the intromission latency of sexually naïve male rats and the extract improved a range of other measured sexual parameters. The results suggest that the extract could enhance libido as well as facilitate erectile function in male rats and that the cyclotide hyen D could contribute to the libido-enhancing activity of this ethnomedicinal herb.

The relation between sexuality and obesity: the role of psychological factors in a sample of obese men undergoing bariatric surgery

Obesity produces a significant deterioration in general and sexual health. The aim of this cross-sectional study was to investigate the impact of obesity on sexuality, illustrating the psychological constructs that may play a significant role in determining sexual functioning and satisfaction. During the psychological assessment for bariatric surgery eligibility, 171 obese men filled out a socio-demographic questionnaire, the International Index of Erectile Function (IIEF), the 20 Item-Toronto Alexithymia Scale, the Symptom Checklist-90-Revised, the Body Uneasiness Test, and the Obesity-related Disability test. A series of hierarchical multiple regression analyses highlighted how obese men sexual desire (F_(11,159) = 10.128, p < 0.001), erectile function (F_(10,160) = 63.578, p < 0.001), orgasmic function (F_(10,160) = 33.967, p < 0.001), intercourse satisfaction (F_(7,163) = 159.752, p < 0.001), and general satisfaction (F_(10,160) = 18.707, p < 0.001) were significantly associated with other IIEF sexual domains, difficulties in identifying feelings, psychopathological symptoms (such as depression and paranoid ideation), body image, and quality of life. Findings are useful for deepening understanding of obese male sexual response, and more generally, for analyzing the complex and multivariate relation between obesity and sexuality, supporting the need of a multidisciplinary approach to obesity care that includes professionals with specific training in sexology.

A Transdiagnostic Approach to Sexual Distress and Sexual Pleasure: A Preliminary Mediation Study with Repetitive Negative Thinking

Sexual distress is a core characteristic of sexual dysfunction; however, little is known about its correlates. In the current study, we aimed to contribute to the understanding of both sexual distress and its positive counterpart, sexual pleasure, by taking a transdiagnostic approach to sexual distress using two types of repetitive negative thinking: worry and rumination. Because sexual activity mostly occurs in a dyadic context, we also looked at the potential mediating effect of co-worry and co-rumination, and we used them as mediators. Our preliminary exploratory quantitative study used a cross-sectional design, with a sample of 206 partnered heterosexual people. We used path analysis with parallel mediation, with structural equation modelling being performed using lavaan designed for R environment. Overall, our results show that repetitive negative thinking is associated with both sexual distress and sexual pleasure, and that neither co-rumination nor co-worry mediates these associations. The exception is the indirect effect of rumination on sexual pleasure that is mediated by co-rumination. These results demonstrate that a transdiagnostic approach to sexual distress is a new field worth exploring, and they contribute to establishing the relevance of a cognitive approach to sexual dysfunction.

Low back pain and sexual disability from the patient's perspective: a qualitative study

PURPOSE

The aim of this qualitative study is to investigate, from patient's perspective, the aspects of the relationship between low back pain and sexual life on physical, psychological and social aspects of individual's life. In addition, this study aims to explore patients' opinions on the role of health care providers in addressing and treating low back pain-related sexual problems.

MATERIALS AND METHODS

Semi-structured interviews were conducted with 26 outpatients referred to physical therapy for subacute or chronic non-specific low back pain; the questions investigated the presence of sexual disability and aspects related to patient's behaviour. Two independent physical therapists, supervised by a third expert physical therapist and a clinical psychologist proficient in qualitative methodology, performed thematic content analysis to identify categories and themes.

RESULTS

Patients with low back pain consider sexual disability severely limiting and correlated to pain. This study emphasized the perception of invalidity, the importance of the relationship with the partner, the emotions and gender roles in the couple, and the relevance for health care providers to take part in the clinical management. The physical therapist is believed to be a qualified figure to address this issue and specific suggestions on sexual activity could be useful.

CONCLUSION

Sexual disability in patients with subacute or chronic LBP acquires an important and individual meaning that can be investigated within the therapeutic context, especially by physical therapists.Implications for RehabilitationSexual disability related to low back pain is considered an important and meaningful topic from the patient's perspective.This reflects the importance of the emotional relationship with the partner.Within the therapeutic context, it is important to provide information to help manage pain during sexual activity.The physical therapist is seen to be a qualified figure to address this issue.

Collection of semen in a dog with partial penectomy followed by successful artificial insemination: case report

ABSTRACT This study describes a case of a dog with a lacerated penile tear treated with partial penectomy followed by successful semen collections for artificial insemination. A 1.5-year-old Jack Russel Terrier with normal libido, genital organs and semen, had a penile laceration after copulation. The dog underwent a partial penectomy without orchiectomy, thus preserving the possibility of semen collection. Semen was successfully collected at 45 and 53 days after surgery, and it was used for artificial insemination of two bitches, one of which became pregnant. Therefore, this report demonstrated that semen may be collected from dogs with partial penectomy for artificial insemination, this technique has the potential to preserve fertility of dogs with penile lesions that require penectomy.

Sexual Desire and Fantasies in the LGBT+ Community: Focus on Lesbian Women and Gay Men

Purpose of Review

The purpose of this review is to summarize the current knowledge around sexual desire, fantasies, and related biopsychosocial factors that may facilitate or obstruct sexual expressions in lesbian women and gay men.

Recent Findings

Sexual desire levels and related problems do not seem significantly different in people who identify as gay or lesbian compared to their heterosexual counterparts. Evidence has shown lesbian women and gay men may have specific desire expressions and biopsychosocial factors influencing their sexual health. This may suggest the importance of deepening the understanding of the unique factors of LGBT+ sexuality and relationships while paying attention to the sociocultural background in which lesbian and gay people grow and develop their identities.

Summary

A lack of specific and unbiased literature on sexual desire and fantasies in gay and lesbian people is reported. Available evidence is controversial and often biased. LG people showed a variety of sexual expressions that are hard to categorize referring to the heteronormative sexual standards that permeate literature and clinical practice. Implications for future research and clinical practice are discussed.

Chemsex in Italy: Experiences of Men Who Have Sex With Men Consuming Illicit Drugs to Enhance and Prolong Their Sexual Activity

BACKGROUND

Chemsex is a novel phenomenon referring to the consumption of illicit drugs to facilitate, enhance, and prolong the sexual experience in men who have sex with men (MSM).

AIM

The present study aims to investigate contexts, patterns of substance use, first chemsex experience, and harm reduction in a group of MSM practicing chemsex in Italy.

METHODS

Thirty MSM involved in chemsex activities were interviewed between February and July 2019.

OUTCOMES

The interviews were conducted using an ad hoc grid exploring general characteristics of Italian chemsex, patterns of substance use, first chemsex experience, and harm reduction opinions.

RESULTS

Chemsex in Italy showed important peculiarities and patterns because of sociocultural background. Chemsex was mainly reported in private venues within couple and group sexual activities. Most participants attended chemsex sessions about 1-2 times per month often concurring with men-only club events. Freebase cocaine emerged among the most relevant substances consumed together with gamma-hydroxybutyrate/gamma-butyrolactone, crystal methamphetamine, and mephedrone. A rare use of injected substances compared with other European Union countries was shown. Given the high prevalence of erectile problems, a large use of phosphodiesterase type 5 inhibitors was reported, and noncoital sexual activities were usually preferred (eg, oral sex, fist fucking). The first chemsex experiences were usually accessed by geolocation-based dating apps and sexual partners and were generally described as positive experiences, with some negative consequences at the end of the session (dysphoric mental states, guilt, craving). Taking part in international gay events seems to favor the first experience of chemsex for some participants. Moreover, some MSM practiced chemsex only abroad or in other cities in Italy so as not to be recognized as chem users in their daily environment.

CLINICAL TRANSLATION

Implications for ad hoc harm reduction programs are discussed.

STRENGTHS & LIMITATIONS

Despite the methodological limitations due to participants' number and the absence of interviews audio recording, results highlighted some relevant characteristics of chemsex in Italy, such as freebase cocaine use, attitudes regarding slamming, geographical movements, and secrecy.

CONCLUSION

The results revealed a need for greater scientific and public attention on chemsex to act with the most specific and effective prevention and harm reduction tools.

Creating and Validating the DESEA Questionnaire for Men and Women

In clinical practice, it is essential to be able to identify hypoactive sexual desire disorder (HSDD), with its different severity levels and assess the influence the subject’s relationship has on the issue. In order to do this, questionnaires are needed that comprise appropriate psychometric properties. We analyzed the psychometric properties and factorial structure of the Sexual Desire and Aversion (DESEA) questionnaire that evaluates sexual desire and interpersonal stress (relationship problems) in male and female couples. A pilot study was conducted with a group of 1583 people. Finally, it included 20,424 Spanish speakers who answered the questionnaire via an online link. The requirements for factor analysis were verified followed by the exploratory and confirmatory factor analysis. The Cronbach’s alpha coefficient calculated the reliability of the test scores at 0.834 in the pilot group and 0.889 in the final group. A 3-factor factorial design explains the 62.08% variance. The KMO (Kaiser-Meyer-Olkin) test (p = 0.904), Bartlett’s test of sphericity (126,115.3; p = 0.000010) and the matrix determinant (0.0020770) verified the appropriateness of the factor analysis. The results show that the DESEA questionnaire is a reliable and valid instrument for evaluating desire and interpersonal stress, both in women and men, in clinical and research contexts.

Sexual Desire and Fantasies in the LGBT+ Community: a Focus on Bisexuals, Transgender, and Other Shades of the Rainbow

Purpose of Review

The purpose of this review is to summarize the current knowledge on sexual desire expressions, sexual orientation, and identity in understudied groups inside the LGBT+ community.

Recent Findings

Sexual desire and related problems have unique expressions in LGBT+ people which influence their sexual health. Emerging sex-positive approaches might be powerful and prominent tools to provide support and education on behalf of safer sex practices and marginalized sexualities. The importance of deepening LGBT+ sexualities and relationships, not only in lesbian women and gay men but also in all the other shades of the rainbow (bisexual, transgender, asexual, fluid, and non-binary/genderqueer identities), is strongly highlighted.

Summary

A lack of literature regarding sexual desire in LGBT+ people is reported. Results are controversial and research is still limited on this topic, with little information available about sexual and health needs of sexual minorities beyond gay and lesbian people.

Haptic and Somesthetic Communication in Sexual Medicine

INTRODUCTION

The word "haptics" refers to sensory inputs arising from receptors in the skin and in the musculoskeletal system, particularly crucial in sexual economy. Haptic stimuli provide information about mechanical properties of touched objects and about the position and motion of the body. An important area in this field is the development of robotic interfaces for communication through the "haptic channel," which typically requires a collaboration between engineers, neuroscientists, and psychologists. Many aspects of human sexuality, such as arousal and intercourse, can be considered from a haptic perspective.

OBJECTIVES

To review the current literature on haptics and somatosensation, and discuss potential applications of haptic interfaces in sexual medicine.

METHODS

Articles for this review were collected based on the results of a bibliographic search of relevant papers in Cochrane Library, Google Scholar, Web of Science, Scopus, and EBSCO. The search terms used, including asterisks, were "haptic∗," "somatosensor∗," "sexual∗," and related terms describing the role of touch, technology, and sexuality. Additional terms included "interface∗," "touch," and "sex∗."

RESULTS

We have provided a functional and anatomical description of the somatosensory system in humans, with special focus on neural structures involved in affective and erotic touch. One interesting topic is the development of haptic interfaces, which are specialized robots generating mechanical signals that stimulate our somatosensory system. We provided an overview on haptic interfaces and evaluated the role of haptics in sexual medicine.

CONCLUSION

Haptics and studies on the neuroscience of the somatosensory system are expected to provide useful insights for sexual medicine and novel tools for sexual dysfunction. In the future, crosstalk between sexology and haptics may produce a novel generation of user-friendly haptic devices generating a higher level of realism and presence in providing stimuli.

The Potential Associations of Pornography Use with Sexual Dysfunctions: An Integrative Literature Review of Observational Studies

This paper reviews the associations between pornography use and sexual dysfunction based on evidence from observational studies. The existing data in this regard mostly derive from cross-sectional investigations and case reports. There is little if no evidence that pornography use may induce delayed ejaculation and erectile dysfunction, although longitudinal studies that control for confounding variables are required for a full assessment. The associations between pornography use and sexual desire may differ between women and men although the existing data is contradictory and causal relationships cannot be established. The strongest evidence is available for the relation of pornography use with decreased sexual satisfaction, although the results of prospective studies are inconsistent. The paper outlines future research prospects beneficial in understanding the nature of associations between pornography use and sexual dysfunctions in men and women.
