Changes in Penile-Vaginal Intercourse Frequency and Sexual Repertoire from 2009 to 2018: Findings from the National Survey of Sexual Health and Behavior

The standardization of a new Explicit Pornographic Picture Set (EPPS)

Pictures with affective content have been extensively used in scientific studies of emotion and sexuality. However, only a few standardized picture sets have been developed that offer explicit images, with most lacking pornographic pictures depicting diverse sexual practices. This study aimed to fill this gap through developing a standardized affective set of diverse pornographic pictures (masturbation, oral sex, vaginal sex, anal sex, group sex, paraphilia) of same-sex and opposite-sex content, offering dimensional affective ratings of valence, arousal, and dominance, as well as co-elicited discrete emotions (disgust, moral and ethical acceptance). In total, 192 pornographic pictures acquired from online pornography platforms and 24 control IAPS images have been rated by 319 participants (Mage = 22.66, SDage = 4.66) with self-reported same- and opposite-sex sexual attraction. Stimuli were representative of the entire affective space, including positively and negatively perceived pictures. Participants showed differential affective perception of pornographic pictures according to gender and sexual attraction. Differences in affective ratings related to participants' gender and sexual attraction, as well as stimuli content (depicted sexual practices and sexes). From the stimuli set, researchers can select explicit pornographic pictures based on the obtained affective ratings and technical parameters (i.e., pixel size, luminosity, color space, contrast, chromatic complexity, spatial frequency, entropy). The stimuli set may be considered a valid tool of diverse explicit pornographic pictures covering the affective space, in particular, for women and men with same- and opposite-sex sexual attraction. This new explicit pornographic picture set (EPPS) is available to the scientific community for non-commercial use.

Has the fall of Roe changed contraceptive access and use? New research from four US states offers critical insights

The overturning of Roe v. Wade in the 2022 Dobbs v. Jackson Women's Health Organization decision has had vast impacts on abortion access across the United States, but less is known about the wider impacts on people's contraceptive access. We draw on cross-sectional survey data representative of reproductive-aged women in Arizona, Iowa, New Jersey, and Wisconsin at two time points-one prior to and one following the Dobbs decision. We examined changes between these two time points in key sexual and reproductive health metrics and, at the post-Dobbs time point, differences in these metrics across age, sexual and gender minority status, nativity, and income status. Between these two time points, we found statistically significant evidence that sexual activity declined, barriers to accessing contraception increased, reports of receiving high-quality contraceptive care decreased, and condom use increased. As continued fallouts of the Dobbs decision on access to abortion occur, this research makes clear that access to broader contraceptive care is worsening. Policies that promote meaningful access to all forms of sexual and reproductive health care must be advanced to support all individuals' right to reproductive autonomy while mitigating inequity and inequality.

Changes in Oral and Anal Sex With Opposite-Sex Partners Among Sexually Active Females and Males Aged 15 to 44 Years in the United States: National Survey of Family Growth, 2011-2019

BACKGROUND

Oral and anal sex with opposite-sex partners is common and associated with sexually transmitted infection (STI) transmission. Trends in these behaviors over the last decade, during which bacterial STI diagnoses have reached historic highs while HIV diagnoses have decreased, are not well understood. We examined recent trends in oral and anal sex and associated condom use with opposite-sex partners among females and males.

METHODS

We analyzed data from 16,926 female and 13,533 male respondents aged 15 to 44 years who reported sex with an opposite-sex partner in the past 12 months from the National Survey of Family Growth, 2011-2019. We used survey-weighted linear or logistic regression to evaluate linear temporal trends in oral and anal sex behaviors.

RESULTS

From 2011-2013 to 2017-2019, reports of oral sex and number of oral sex partners in the past 12 months increased among females (85.4% in 2011-2013 to 89.4% in 2017-2019; odds ratio [OR], 1.05 [95% confidence interval {CI}, 1.02-1.09], and β = 0.014 [95% CI, 0.005-0.023]; respectively) but not males (ranges, 87.9%-89.1%; 1.27-1.31). Condom use at last oral sex decreased among both females and males (6.3%-4.3%: OR, 0.93 [95% CI, 0.88-0.99]; 5.9%-4.4%: OR, 0.95 [95% CI, 0.91-1.00]). Anal sex (ranges, 21.0%-23.3% [females] and 23.3%-24.6% [males]), number of anal sex partners (females, 0.22-0.25; males, 0.26-0.30), and condom use at last anal sex (females, 15.3%-18.2%; males, 27.0%-28.7%) remained stable.

CONCLUSIONS

The frequency of oral and anal sex with opposite-sex partners among U.S. 15- to 44-year-olds, paired with limited and-for oral sex-decreasing condom use, demonstrates the need to understand the role of these behaviors in increasing STI diagnosis rates and the potential role of extragenital screening and condoms in reducing STI transmission.

The Role of Mutual Masturbation within Relationships: Associations with Sexual Satisfaction and Sexual Self-Esteem

Objectives

We explored mutual masturbation among women and men and investigated associations with sexual satisfaction and sexual self-esteem.

Methods

117 women and 151 men (Mage = 29.7 years), mostly heterosexual, all in current relationships, completed an online survey covering experiences of solo and partnered sexual activities, feelings about mutual masturbation, sexual self-esteem, and sexual satisfaction.

Results

Mutual masturbation was common among both genders. Men reported significantly higher positive feelings about mutual masturbation than women. Recent mutual masturbation was positively associated with sexual satisfaction but not with sexual self-esteem.

Conclusions

These findings have implications for sex and couple therapy and research.

Changes in sexually transmitted infections-related sexual risk-taking among young Croatian adults: a 2005-2021 three-wave population-based study

AIM

To assess the prevalence and dynamics of risky sexual behaviors among Croatian emerging adults in the 2005-2021 period.

METHODS

Three surveys were conducted on large-scale national samples of young adults aged 18-24 in 2005 (N=1092) and 18-25 in 2010 and 2021 (N=1005 and N=1210, respectively). The 2005 and 2010 studies were conducted with face-to-face interviews on stratified probabilistic samples. The 2021 study was conducted by computer-assisted web-interviewing on a quota-based random sample from the largest national online panel.

RESULTS

Compared with 2005 and 2010, the age at coital debut increased for both genders in 2021 (by a median of one year, to 18 years, and by a mean of half a year, to 17.5 years, in men and to 17.9 in women). In the 2005-2021 period, condom use increased by about 15% both at first intercourse (to 80%) and in consistent use (to 40% in women and 50% in men). When we controlled for basic socio-demographics, Cox and logistic regressions indicated that, for both genders, in 2005 and 2010 compared with 2021, the risks/odds were significantly higher for reporting an earlier sexual debut (adjusted hazard ratio 1.25-1.37), multiple sexual partners (adjusted odds ratio [AOR] 1.62-3.31), and concurrent relationships (AOR 3.36-4.64), while the odds were lower for condom use at first sexual intercourse (AOR 0.24-0.46) and consistently (AOR 0.51-0.64).

CONCLUSION

Risky sexual behaviors decreased in the 2021 survey compared with the previous two waves, in both genders. Nonetheless, sexual risk-taking is still frequent among young Croatian adults. The introduction of sexuality education and other national-level public health interventions to reduce sexual risk-taking thus remains a public health imperative.

Masturbation Prevalence, Frequency, Reasons, and Associations with Partnered Sex in the Midst of the COVID-19 Pandemic: Findings from a U.S. Nationally Representative Survey

Despite well-documented individual, relational, and health benefits, masturbation has been stigmatized and is understudied compared to partnered sex. In a US nationally representative survey of adults, we aimed to: (1) assess the prevalence and frequency of participants' prior-year masturbation, (2) describe reasons people give for not masturbating, (3) describe reasons people give for masturbating, and (4) examine the association between masturbation frequency and actual/desired partnered sex frequency in the prior year. Significantly more men than women reported lifetime masturbation, past month masturbation, and greater masturbation frequency. The most frequently endorsed reasons for masturbating related to pleasure, feeling "horny," stress relief, and relaxation. The most frequently endorsed reasons for not masturbating were lack of interest, being in a committed relationship, conflict with morals or values, or being against one's religion. Among women, those who desired partnered sex much more often and a little more often were 3.89 times (95% CI: 2.98, 5.08) and 2.07 times (95% CI: 1.63, 2.62), respectively, more likely to report higher frequencies of past-year masturbation than those who desired no change in their partnered sex frequency. Among men, those who desired partnered sex much more often and a little more often were 4.40 times (95% CI: 3.41, 5.68) and 2.37 times (95% CI: 1.84, 3.06), respectively, more likely to report higher frequencies of past-year masturbation activity than those who reported that they desired no change in their current partnered sex frequency. Findings provide contemporary U.S. population-level data on patterns of adult masturbation.

Sexual Repertoire, Duration of Partnered Sex, Sexual Pleasure, and Orgasm: Findings from a US Nationally Representative Survey of Adults

In a confidential U.S. nationally representative survey of 2,525 adults (1300 women, 1225 men), we examined participants' event-level sexual behaviors, predictors of pleasure and orgasm, and perceived actual and ideal duration of sex, by gender and age. Event-level kissing, cuddling, vaginal intercourse, and oral sex were prevalent. Sexual choking was more prevalent among adults under 40. While women and men reported a similar actual duration of sex, men reported a longer ideal duration. Participants with same-sex partners reported a longer ideal duration than those with other-sex partners. Finally, findings show that gendered sexual inequities related to pleasure and orgasm persist.

Exploring the Ownership of Child-Like Sex Dolls

There is a fervent social debate ongoing that relates to the ownership of child-like sex dolls. On the one hand, some proponents of dolls suggest that they offer a safe sexual outlet for minor-attracted people (MAPs) and could be used in efforts to prevent the sexual abuse of children. On the other side of the debate, child-like dolls are seen as articles that sexualize children, encourage deviant fantasies, and increase offending risk. To date, no empirical analyses have been undertaken with people who own such dolls. In this paper, we present data from child-like sex doll owners (n = 85) and MAPs who do not own dolls (n = 120) recruited from online forums visited by people who own sex dolls or forums for people with sexual attractions to children. Specifically, we compared their psychological characteristics and proclivities for sexual aggression. Among non-owners, 79.2% of participants declared an interest in owning a sex doll, which is higher than the 20-40% rate reported in adult-attracted samples of non-owners. We found few differences between the groups on most personality variables, with doll owners being less antisocial and anxiously attached than non-owners, but exhibiting more schizotypal traits. Related to offending proclivities, doll ownership was associated with lower levels of sexual preoccupation and self-reported arousal to hypothetical abuse scenarios, but higher levels of sexually objectifying behaviors and anticipated enjoyment of sexual encounters with children. We discuss these data in relation to a functional model of child-like sex doll ownership among MAPs.

Relationships between Penile-Vaginal Intercourse Frequency and Condom/Contraceptive Use from 2009 to 2018: Findings from the National Survey of Sexual Health and Behavior

Objectives

To examine changes over time in event-level condom/contraceptive use and the association between past year penile-vaginal intercourse frequency and event-level condom/contraceptive use.

Methods

Data were from the 2009 and 2018 National Survey of Sexual Health and Behavior, an online probability survey of U.S. adolescents and adults.

Results

Use of condoms and highly effective hormonal contraceptives decreased while long-acting reversible contraceptive use increased from 2009 to 2018 among adults. Increased penile-vaginal intercourse frequency was associated with decreased use of most contraceptive methods but an increase in condom use for adolescents.

Conclusions

Sexual frequency should be considered when assessing condom/contraceptive use.
