Abstract
This study investigated sexual fluidity in attractions and subsequent fluidity in sexual identities, its associations with sexual orientation identity labels, and self-reported likelihood of future change in sexual identity labels in a sample of same-sex attracted Malaysian women and men. Participants completed an online questionnaire measuring sexual fluidity in attractions and sexual identity, sexual orientation identity labels and likelihood of future change in identity labels. Sexual fluidity in attractions was reported by 72% of women and 64% of men, with 44% of women and 38% of men reporting subsequent fluidity in sexual orientation identities. There were no significant gender differences observed in the frequency of sexual fluidity in attractions and change in sexual identity labels. There were also no significant gender differences in the self-reported likelihood of future change in sexual identity labels. Sexual fluidity was found to be associated with sexual identity labels representing non-exclusive sexual attractions for both men and women. Findings provide preliminary support for the presence of facilitative environments within a largely conservative and restrictive sociocultural and political landscape.

Abstract
Guidelines concerning the potentially harmful effects of scientific studies have historically focused on ethical considerations for minimizing risk for participants. However, studies can also indirectly inflict harm on individuals and social groups through how they are designed, reported, and disseminated. As evidenced by recent criticisms and retractions of high-profile studies dealing with a wide variety of social issues, there is a scarcity of resources and guidance on how one can conduct research in a socially responsible manner. As such, even motivated researchers might publish work that has negative social impacts due to a lack of awareness. To address this, we propose 10 simple rules for researchers who wish to conduct socially responsible science. These rules, which cover major considerations throughout the life cycle of a study from inception to dissemination, are not aimed as a prescriptive list or a deterministic code of conduct. Rather, they are meant to help motivated scientists to reflect on their social responsibility as researchers and actively engage with the potential social impact of their research.

Abstract
Human asexuality has been defined as a lack of sexual attraction to others, although its nature is not well understood. Asexual men's genital and subjective sexual arousal patterns were compared to sexual men's to better understand asexual men's sexual response patterns. Using a penile plethysmograph to measure genital arousal, 20 asexual, 27 heterosexual, and 22 gay cisgender men (M age = 28.28, SD = 9.41) viewed erotic films depicting sexual activity or masturbation, and a subsample engaged in sexual fantasy of their choosing. Questionnaires assessing sexual function and behavior were also completed. Asexual men scored lower on sexual desire and orgasmic function, higher on sexual aversion, and did not differ on overall sexual satisfaction. Compared with gay and heterosexual men, asexual men demonstrated lower genital and subjective sexual arousal to the erotic films but displayed similar sexual arousal when engaging in sexual fantasy. Asexual men's lower levels of sexual excitation rather than their higher levels of sexual inhibition were associated with lower responses to the erotic films. These findings suggest asexual men have preferred sexual stimuli that differ from sexual men and have a similar capacity for sexual arousal as sexual men. Collectively these findings add to a growing literature aiming to understand the nature of asexuality.

Abstract
Longitudinal work suggests that sexual orientation can change over time in men and women. These studies, however, may be susceptible to the bias of self-report. The current study therefore examined self-reported sexual orientation in addition to an objective correlate: genital arousal to erotic videos showing males or females. For 52 men (19 heterosexual, 19 bisexual, 14 homosexual) and 67 women (31 heterosexual, 18 bisexual, 18 homosexual), these measures were taken twice, with approximately 1 year between sessions. For self-reported sexual orientation, women reported lower relative stability (weaker correlation) than men over time, even though women did not change more overall (no stronger mean difference) than men between sessions. Bisexual individuals reported lower relative stability and more mean change than heterosexual and homosexual individuals. For genital arousal, across all groups, response patterns were correlated over time to a similar extent and showed little difference between sessions. Moreover, change in self-reported sexual orientation did not correspond with the change in genital arousal, regardless of sex. Perhaps self-reports overestimate changes in sexual orientation, since these changes were not reflected in physiological sexual response.

Sexual Orientation Across Porn Use, Sexual Fantasy, and In-Person Sexuality: Visualizing Branchedness and Coincidence via Sexual Configurations Theory. ARCHIVES OF SEXUAL BEHAVIOR 2022; 51:1201-1219.

Abstract
Sexual orientation describes sexual interests, approaches, arousals, and attractions. People experience these interests and attractions in a number of contexts, including in-person sexuality, fantasy, and porn use, among others. The extent to which sexual orientation is divergent (branched) and/or overlapping (coincident) across these, however, is unclear. In the present study, a gender/sex and sexually diverse sample (N = 30; 15 gender/sex/ual minorities and 15 majorities) manipulated digital circles representing porn use, in-person sexuality, and fantasy on a tablet during in-person interviews. Participants used circle overlap to represent the degree of shared sexual interests across contexts and circle size to indicate the strength and/or number of sexual interests within contexts. Across multiple dimensions of sexual orientation (gender/sex, partner number, and action/behavior), we found evidence that sexual interests were both branched and coincident. These findings contribute to new understandings about the multifaceted nature of sexual orientations across contexts and provide a novel way to measure, conceptualize, and understand sexual orientation in context.

Abstract
Objective measures of sexual interest are important for research on human sexuality. There has been a resurgence in research examining pupil dilation as a potential index of sexual orientation. We carried out a meta-analytic review of studies published between 1965 and 2020 (Mdn year = 2016) measuring pupil responses to visual stimuli of adult men and women to assess sexual interest. Separate meta-analyses were performed for six sexual orientation categories. In the final analysis, 15 studies were included for heterosexual men (N = 550), 5 studies for gay men (N = 65), 4 studies for bisexual men (N = 124), 13 studies for heterosexual women (N = 403), and 3 studies for lesbian women (N = 132). Only heterosexual and gay men demonstrated discrimination in pupillary responses that was clearly in line with their sexual orientation, with greater pupil dilation to female and male stimuli, respectively. Bisexual men showed greater pupil dilation to male stimuli. Although heterosexual women exhibited larger pupils to male stimuli compared to female stimuli, the magnitude of the effect was small and non-significant. Finally, lesbian women displayed greater pupil dilation to male stimuli. Three methodological moderators were identified-the sexual explicitness of stimulus materials, the measurement technique of pupillary response, and inclusion of self-report measures of sexual interest. These meta-analyses are based on a limited number of studies and are therefore preliminary. However, the results suggest that pupillary measurement of sexual interest is promising for men and that standardization is essential to gain a better understanding of the validity of this measurement technique for sexual interest.

Abstract
This study examined demographic and geographic differences in facial masculinity preferences among gay and bisexual men in China. The final sample included 2595 participants whose data were obtained from four published data sets and one unpublished data set. Demographic variables included sexual self-label, sexual orientation, age, educational level, and occupational status. Geographic variables were classified based on the IP addresses of respondents including North-South division, administrative division, economic regional division, and modernization division. There were significant differences in facial masculinity preferences in demographic variables. Gay men preferred more masculinized faces than did bisexual men. "Tops" preferred feminized faces, whereas "bottoms" and "versatiles" preferred masculinized faces. Participants aged 20-29 years preferred more masculinized faces than did those aged 16-19 years and older than 30. Also, the results indicated significant differences in facial masculinity preferences in geographic variables. Participants living in South China preferred more masculinized faces than did those living in North China. Concerning administrative division, individuals living in South China (Guangdong, Guangxi, Fujian, and Jiangxi) preferred more masculinized faces than did those living in other regions. Participants living in first-tier cities (Beijing, Shanghai, Guangzhou, and Shenzhen) preferred more masculinized faces than did those living in other cities. The findings implicated context-dependent variability in facial masculinity preferences among gay and bisexual men; facial trait-attribution processes may contribute to these individual differences.

Abstract
Previous research has examined the phenomenon of "sexual fluidity," but there is no current consensus on the specific meaning and operationalization of this construct. The present study used a sample of 76 women with diverse sexual orientations to compare four different types of sexual fluidity: (1) fluidity as overall erotic responsiveness to one's less-preferred gender, (2) fluidity as situational variability in erotic responsiveness to one's less-preferred gender, (3) fluidity as discrepancy between the gender patterning of sexual attractions and the gender patterning of sexual partnering, and (4) fluidity as instability in day-to-day attractions over time. We examined how these four types of fluidity relate to one another and to other features of women's sexual profiles (bisexual vs. exclusive patterns of attraction, sex drive, interest in uncommitted sex, age of sexual debut, and lifetime number of sexual partners). The four types of fluidity were not correlated with one another (with the exception of the first and fourth), and each showed a unique pattern of association with other features of women's sexual profiles. The only type of fluidity associated with bisexuality was overall erotic responsiveness to the less-preferred gender. The findings demonstrate that future research on sexual fluidity should distinguish between its different forms.

Abstract
Mostly heterosexual men describe themselves as slightly bisexual, with predominant sexual attraction to women but occasional attraction to men. After "completely heterosexual," "mostly heterosexual" is the most common male sexual orientation, by self-report. However, self-reported bisexual feelings among men can diverge from patterns of genital arousal, an objective measure of sexual interest with high validity. We compared 49 mostly heterosexual and 50 completely heterosexual men's patterns of genital and subjective sexual arousal to male and female erotic stimuli. In addition, we compared these groups on relevant self-report measures pertaining to sexual feelings, identity, and behavior. Results supported increased bisexual arousal with respect to self-report and genital arousal pattern among the mostly heterosexual men, compared with the completely heterosexual men. Furthermore, mostly heterosexual men reported more childhood gender nonconformity, greater male sex partners, and less self-reported disgust or aversion to sex acts with men. "Mostly heterosexual" appears to be a gradation of male sexual orientation associated with unique genital arousal patterns, among other correlates.

Abstract
Abstract
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.

Abstract
Distinct manifestations of sexual behavior are conceived as separate phenotypes. Each sexual phenotype is assumed to be associated with a characteristic brain. These notions have justified the phenotyping of heterosexual copulator males based upon their ejaculation's latencies (EL) or frequencies (i.e., cumulative ejaculation number; EN). For instance, men and male rats showing premature, normal or retarded ejaculation are assumed to be distinctive endophenotypes. This concept, nonetheless, contradicts past and recent evidence that supports that sexual behavior is highly variable within each sex, and that the brain sexual functional morphology represents an intricate sexual phenotypic mosaic. Hence, for ejaculatory male endophenotypes to be considered as a valid biological concept, it must show internal consistency at various levels of organization (including genetic architectures), after being challenged by intrinsic and/or extrinsic factors. We then judged the internal consistency of the presumed ejaculatory endophenotypes by assessing whether copulatory behavior and the expression of copulation relevant genes and brain limbic structures are specific to each of the presumed EL- or EN-ejaculatory endophenotypes. To do this, copulating male rats were first phenotyped in groups consistently displaying short, average or long ejaculation latencies or very high, high, average, low or very low EN, based in their copulatory performance. Then, the internal consistency of the presumed EL- or EN-endophenotypes was tested by introducing as covariates of phenotyping other copulatory parameters (e.g., number of intromissions) in addition to EL or EN, or by analyzing the expression levels of genes encoding for estrogen receptor alpha, progesterone receptor, androgen receptor, aromatase, DNA methyl-transferase 3a and DNA methyl-transferase 1 in the amygdala, medial preoptic area, ventromedial hypothalamus and olfactory bulb. We found that even though there were group-level differences in all the variables that were studied, these differences did not add-up to create the presumed EL- or EN-ejaculatory endophenotypes. In fact, the extensive overlapping of copulatory parameters and expression levels of copulation relevant genes in limbic structures across EL- or EN-phenotyped copulating male rats, is not consistent with the hypothesis that distinct ejaculatory endophenotypes exist and that they are associated with specific brain characteristics.

Abstract
Ambiphilic (or bisexual) men describe feelings of sexual attraction to both men and women. However, physiological measures of arousal have failed to show a consistent pattern of arousal to both genders. We measured men's automatic associations between the concept of sex (represented by words) and the concepts of men versus women (represented by images) via the Implicit Association Test (IAT) and a priming task. On the IAT, gynephilic men (N = 32) were faster for women-sex pairings, androphilic men (N = 18) were faster for men-sex pairings, while ambiphilic men (N = 20) showed no bias toward either gender. We then isolated the concepts of "men" and "women" by comparing them separately against neutral images. In contrast to both the gynephilic or androphilic men, ambiphilic men showed sexual associations to both men and women. On the priming task, ambiphilic men showed faster responses to sex words, but slower responses to not-sex words, when primed with pictures of either men or women compared to when primed by neutral images. The results from all the experimental tasks suggest that ambiphilic men have a pattern of sexual association that is different from both gynephilic and androphilic men and represents a sexual attraction to both men and women.

Abstract
In Samoa, feminine natal males who possess male-typical genitalia are known locally as fa'afafine. Some Samoan men express sexual interest in fa'afafine, whereas others do not. To assess the sexual orientation of men who are sexually interested in fa'afafine, we collected sexual attraction ratings and viewing times of Samoan men's and women's faces. Study 1 (N = 130) focused on men who were insertive or versatile during anal sex with fa'afafine partners. These men were compared to each other, as well as to males (i.e., men and fa'afafine) who were exclusively sexually interested in either women or men. Study 2 (N = 180) compared men who had sex with fa'afafine and women; men who had sex with fa'afafine, women, and men; and men who had sex with fa'afafine and men. These men were compared to each other, as well as to males who were exclusively sexually interested in either women or men. These studies suggest that men who have sex with fa'afafine are a heterogeneous group. A small portion of the men who are sexually interested in fa'afafine shows a relatively bisexual pattern of sexual attraction ratings and viewing times, namely men who have sex with fa'afafine, men, and women. In contrast, a larger number of men who were sexually interested in fa'afafine responded in a manner similar to men who were exclusively sexually interested in either women or men. The present research suggests that additional insights into male sexual orientation can be garnered by focusing on how sexuality is expressed in non-Western cultural contexts.

Wang Y, Wu H, Sun ZS. The biological basis of sexual orientation: How hormonal, genetic, and environmental factors influence to whom we are sexually attracted. Front Neuroendocrinol 2019; 55:100798. [PMID: 31593707 DOI: 10.1016/j.yfrne.2019.100798] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/16/2019] [Revised: 09/29/2019] [Accepted: 10/03/2019] [Indexed: 12/11/2022]
Abstract
Humans develop relatively stable attractions to sexual partners during maturation and present a spectrum of sexual orientation from homosexuality to heterosexuality encompassing varying degrees of bisexuality, with some individuals also displaying asexuality. Sexual orientation represents a basic life phenomenon for humans. However, the molecular mechanisms underlying these diverse traits of sexual orientation remain highly controversial. In this review, we systematically discuss recent advancements in sexual orientation research, including those related to measurements and associated brain regions. Current findings regarding sexual orientation modulation by hormonal, genetic, maternal immune system, and environmental factors are summarized in both human and model systems. We also emphasize that future studies should recognize the differences between males and females and pay more attention to minor traits and the epigenetic regulation of sexual orientation. A comprehensive view of sexual orientation may promote our understanding of the biological basis of sex, and that of human reproduction, and evolution.

Abstract
Some research suggests that bisexual-identified men show bisexual genital arousal, whereas other research indicates monosexual arousal: they are aroused to one sex only. These seemingly contradictory findings may be due to the type of men identifying as bisexual and the performed analyses. We examined whether both bisexual and monosexual arousal patterns could co-occur within the same sample. 114 men of different sexual orientations viewed erotic videos of males or females while their penile circumference was measured. On average, bisexual-identified men were more aroused to males than females, and especially if they identified as "bisexual leaning gay." However, also on average, bisexual men showed bisexual arousal, and especially if they were "bisexual leaning straight". Furthermore, there was more variability in the arousal patterns of bisexual-identified men, compared with other men. Based on their physiological sexual arousal, bisexual men appear to be a more diverse group than men who identified as heterosexual or homosexual.

Abstract
This study investigated whether pupil size during the viewing of images of adults and children reflects the sexual orientation of heterosexual, homosexual, and bisexual men (n = 100, Mage = 22). More specifically, we explored whether this measure corresponds with sexual age preferences for adults over children in nonpedophilic men. In general, results across three experiments, in which observers freely viewed or rated the sexual appeal of person images, suggest that pupil dilation to sexual stimuli is an indicator of sexual orientation toward adults. Heterosexual men's pupils dilated most strongly to adults of the other sex, homosexual men dilated most strongly to adults of the same sex, and bisexual men showed an intermediate pattern. Dilation to adults was substantially stronger than dilation to younger age groups. Sexual appeal ratings for images of adults and children also correlated with pupil responses, suggesting a direct link between pupil dilation and sexual interest. These findings provide support for pupil dilation as a measure of sex- and age-specific sexual preferences.

Abstract
Measures of sexual interest tend to be more gender-specific in heterosexual men than in heterosexual women. Cognitive measures, such as viewing time to attractive stimuli, may also show similar patterns of gender-specificity or nonspecificity among men and women and thus serve as useful adjuncts to more direct measures of sexual interest. The objectives of the present research were to determine the extent of gender-specificity in women's viewing times for female pictures (varying in their perceived physical attractiveness) and explore the influence of social comparison of physical appearance on these patterns of responses. In Study 1, we recorded only women's viewing times for pictures of both genders, measured self-reported menstrual cycle phase, and manipulated the waist-to-hip ratio of the women in the female pictures. In Study 2, we recorded women's and men's viewing times, self-reported sexual attraction to pictures of males and females, and physical appearance social comparison. Study 1 found that heterosexual women's viewing time toward female pictures was not associated with manipulation of the perceived attractiveness of those pictures. Study 2 found that heterosexual men were more gender-specific than heterosexual women in their viewing time patterns. We also found that reported sexual attraction and physical appearance social comparison were associated with heterosexual women's viewing times for female pictures, while heterosexual men's viewing times were associated with sexual attraction only. Our results are discussed in relation to the utility of viewing time as an indicator of visual attention toward attractive or sexually appealing visual stimuli.

Abstract
Studies of subjective and genital sexual arousal in monosexual (i.e. heterosexual and homosexual) men have repeatedly found that erotic stimuli depicting men’s preferred sex produce strong responses, whereas erotic stimuli depicting the other sex produce much weaker responses. Inconsistent results have previously been obtained in bisexual men, who have sometimes demonstrated distinctly bisexual responses, but other times demonstrated patterns more similar to those observed in monosexual men. We used fMRI to investigate neural correlates of responses to erotic pictures and videos in heterosexual, bisexual, and homosexual men, ages 25–50. Sixty participants were included in video analyses, and 62 were included in picture analyses. We focused on the ventral striatum (VS), due to its association with incentive motivation. Patterns were consistent with sexual orientation, with heterosexual and homosexual men showing female-favoring and male-favoring responses, respectively. Bisexual men tended to show less differentiation between male and female stimuli. Consistent patterns were observed in the whole brain, including the VS, and also in additional regions such as occipitotemporal, anterior cingulate, and orbitofrontal cortices. This study extends previous findings of gender-specific neural responses in monosexual men, and provides initial evidence for distinct brain activity patterns in bisexual men.

Abstract
We examined the stability of same-sex and other-sex attractions among 294 heterosexual, lesbian, gay, and bisexual men and women between the ages of 18 and 40 years. Participants used online daily diaries to report the intensity of each day's strongest same-sex and other-sex attraction, and they also reported on changes they recalled experiencing in their attractions since adolescence. We used multilevel dynamical systems models to examine individual differences in the stability of daily attractions (stability, in these models, denotes the tendency for attractions to "self-correct" toward a person-specific setpoint over time). Women's attractions showed less day-to-day stability than men's, consistent with the notion of female sexual fluidity (i.e., heightened erotic sensitivity to situational and contextual influences). Yet, women did not recollect larger post-adolescent changes in sexual attractions than did men, and larger recollected post-adolescent changes did not predict lower day-to-day stability in the sample as a whole. Bisexually attracted individuals recollected larger post-adolescent changes in their attractions, and they showed lower day-to-day stability in attractions to their "less-preferred" gender, compared to individuals with exclusive same-sex or exclusive other-sex attractions. Our results suggest that both gender and bisexuality have independent influences on sexual fluidity, but these influences vary across short versus long timescales, and they also differ for attractions to one's "more-preferred" versus "less-preferred" gender.

Abstract
Snowden, Wichter, and Gray (2008) demonstrated that an Implicit Association Test and a Priming Task both predicted the sexual orientation of gynephilic and androphilic men in terms of their attraction biases towards pictures of nude males and females. For both measures, relative bias scores were obtained, with no information on the separate response biases to each target gender. The present study sought to extend this research by assessing both relative and individual implicit biases using the Implicit Relational Assessment Procedure (IRAP). An explicit measure screened for men with androphilic (n = 16) or gynephilic (n = 16) orientations on the dimensions of "sexual attraction," "sexual behavior," "sexual fantasies," "hetero/gay lifestyle," and "self identification." The IRAP involved responding "True" or "False" to pictures of nude males and females as either attractive or unattractive. Participants were required to respond in a manner consistent with their reported sexual orientation for half of the IRAP's test blocks and inconsistent for the other half. Response latencies were recorded and analyzed. The IRAP revealed a non-orthogonal pattern of biases across the two groups and had an excellent ability to predict sexual orientation with areas under the curves of 1.0 for the relative bias score and .94 and .95 for the bias scores for the male and female pictures, respectively. Correlations between the IRAP and explicit measures of sexual orientation were consistently high. The findings support the IRAP as a potentially valuable tool in the study of sexual preferences.

Abstract
We review scientific research and legal authorities to argue that the immutability of sexual orientation should no longer be invoked as a foundation for the rights of individuals with same-sex attractions and relationships (i.e., sexual minorities). On the basis of scientific research as well as U.S. legal rulings regarding lesbian, gay, and bisexual (LGB) rights, we make three claims: First, arguments based on the immutability of sexual orientation are unscientific, given what we now know from longitudinal, population-based studies of naturally occurring changes in the same-sex attractions of some individuals over time. Second, arguments based on the immutability of sexual orientation are unnecessary, in light of U.S. legal decisions in which courts have used grounds other than immutability to protect the rights of sexual minorities. Third, arguments about the immutability of sexual orientation are unjust, because they imply that same-sex attractions are inferior to other-sex attractions, and because they privilege sexual minorities who experience their sexuality as fixed over those who experience their sexuality as fluid. We conclude that the legal rights of individuals with same-sex attractions and relationships should not be framed as if they depend on a certain pattern of scientific findings regarding sexual orientation.

Abstract
Summary Ongoing political controversies around the world exemplify a long-standing and widespread preoccupation with the acceptability of homosexuality. Nonheterosexual people have seen dramatic surges both in their rights and in positive public opinion in many Western countries. In contrast, in much of Africa, the Middle East, the Caribbean, Oceania, and parts of Asia, homosexual behavior remains illegal and severely punishable, with some countries retaining the death penalty for it. Political controversies about sexual orientation have often overlapped with scientific controversies. That is, participants on both sides of the sociopolitical debates have tended to believe that scientific findings—and scientific truths—about sexual orientation matter a great deal in making political decisions. The most contentious scientific issues have concerned the causes of sexual orientation—that is, why are some people heterosexual, others bisexual, and others homosexual? The actual relevance of these issues to social, political, and ethical decisions is often poorly justified, however.

Abstract
This qualitative study investigated the sexual self-schemas and masculinity ideologies of 20 bisexual men. Sexual self-schema was defined as a cognitive generalization about sexual aspects of the self, as derived from past experience and sociocultural context, which guides current experiences and facilitates the processing of sexual information. In-depth interviews, a focus group, documentary evidence, and grounded theory analysis were used. Categories were coded and analyzed, revealing two models. The first, the sexual self-schema of bisexual men, is an eight-category model of the bisexual male sexual self-schema describing men’s relationships with other men and with women, as well as attitudes about themselves. The second model, the process of emerging awareness of bisexual attraction, outlines how sexual and romantic relationship experiences lead to bisexual sexual orientation identity. The two theoretical models depict how bisexual men understand their own sexual self-schemas. Implications for counseling psychology research and practice are addressed.

Abstract
Introduction Time spent viewing visual sexual stimuli (VSS) has the potential to habituate the sexual response and generalize to the partner context. Aim The aim of this study was to examine whether the time spent viewing VSS is related to sexual responsiveness felt in the laboratory or with a sexual partner. Methods Nontreatment-seeking men (N = 280) reported their weekly average VSS viewing in hours. VSS hours were examined in relation to the sexual arousal experienced while viewing a standardized sexual film in the laboratory and erectile problems experienced with a sexual partner. Main Outcome Measures Self-reported sexual arousal in response to sexual films and erectile problems on the International Index of Erectile Function were the main outcome measures. Results More hours viewing VSS was related to stronger experienced sexual responses to VSS in the laboratory, was unrelated to erectile functioning with a partner, and was related to stronger desire for sex with a partner. Conclusions VSS use within the range of hours tested is unlikely to negatively impact sexual functioning, given that responses actually were stronger in those who viewed more VSS.

Abstract
The present study assessed the gender-specificity of sexual interest of bisexually-identified men and women, compared to gay men and lesbian women. Utilizing viewing time as a measure of sexual interest, self-identified bisexual men (N = 50) and women (N = 54) rated the sexual appeal of sexually provocative pictures while the amount of time spent viewing each picture was inconspicuously measured. As hypothesized, bisexual men and women demonstrated a pattern of sexual interest that was significantly less gender-specific than that of a gay/lesbian sample. That is, bisexual men and women (1) viewed other-sex pictures significantly longer than gay men/lesbian women viewed other-sex pictures and (2) rated other sex pictures significantly more sexually appealing than gay men/lesbians rated other-sex pictures. Additionally, the difference in viewing times and appeal ratings between male and female sexual stimuli for bisexuals was significantly less than the difference evidenced by gay men and lesbians. These findings suggest that self-identified bisexual men and women demonstrate a truly bisexual pattern of sexual interest, characterized by greater other-sex attraction and less gender-specificity than is true for gay men and lesbians.

Abstract
Men's sexual arousal is largely dependent on the actor's gender in a sexual stimulus (gender-specific), whereas for women, particularly androphilic women, arousal is less dependent on gender (gender-nonspecific). According to information-processing models of sexual response, sexual arousal requires that attention be directed toward sexual cues. We evaluated whether men's and women's self-reported attention to sexual stimuli of men or women were consistent with genital responses and self-reported arousal. We presented gynephilic men (n = 21) and women (n = 22) and androphilic men (n = 16) and women (n = 33) with audiovisual stimuli depicting men or women engaged in sexual activities. Genital responses were continuously recorded and, following each stimulus, participants reported the amount of attention paid to the video and feelings of sexual arousal. Self-reported attention was gender-specific for men and gender-nonspecific for women, and generally mirrored genital responses and self-reported arousal. Gender-specificity of genital responses significantly predicted gender-specificity of self-reported arousal; however, for men only, this effect was significantly mediated by gender-specificity of self-reported attention. Gender differences in gender-specificity of sexual arousal may be partially accounted for by differences in gender-specificity of self-reported attention, although attention may play a greater role in men's sexual arousal than women's.

Abstract
Do self-identified bisexual men and women actually show bisexual patterns of sexual attraction and interest? To answer this question, I studied bisexual men's and women's sexual attraction to photographed male and female "swimsuit models" that varied in attractiveness. Participants (663 college students and gay pride attendees, including 14 self-identified bisexual men and 17 self-identified bisexual women) rated their degree of sexual attraction to 34 male and 34 female swimsuit models. Participants' viewing times to models were unobtrusively assessed. Results showed that bisexual men and women showed bisexual patterns of attraction and viewing times to photo models, which strongly distinguished them from same-sex heterosexual and homosexual participants. In contrast to other groups, which showed evidence of greater male than female category specificity, bisexual men and women did not differ in category specificity. Results suggest that there are subsets of men and women who display truly bisexual patterns of sexual attraction and interest.

Abstract
Many sexual minority individuals attempt suicide each year, but little is known about the suicidality of individuals who are questioning their sexual orientation. This study assessed suicidal ideation and attempts of questioning individuals compared to lesbian/gay, bisexual, and heterosexual individuals. This cross-sectional study enrolled participants (N = 2,841) from a community health center. Questioning (OR = 4.286, 95% CI [2.119-8.671]), lesbian/gay (OR = 3.024, 95% CI [2.351-3.890]), and bisexual (OR = 4.389, 95% CI [2.942-6.575]) individuals had significantly greater odds of considering suicide compared to heterosexuals. However, questioning individuals had non-significant odds of attempting suicide compared to heterosexuals. We discuss possible explanations for these findings.

Abstract
Recent research suggests profound sex and sexual orientation differences in sexual response. These results, however, are based on measures of genital arousal, which have potential limitations such as volunteer bias and differential measures for the sexes. The present study introduces a measure less affected by these limitations. We assessed the pupil dilation of 325 men and women of various sexual orientations to male and female erotic stimuli. Results supported hypotheses. In general, self-reported sexual orientation corresponded with pupil dilation to men and women. Among men, substantial dilation to both sexes was most common in bisexual-identified men. In contrast, among women, substantial dilation to both sexes was most common in heterosexual-identified women. Possible reasons for these differences are discussed. Because the measure of pupil dilation is less invasive than previous measures of sexual response, it allows for studying diverse age and cultural populations, usually not included in sexuality research.

Abstract
Self-identified bisexual men report high sexual arousal to both male and female stimuli, but no study to date has compellingly demonstrated that such men have a bisexual pattern of genital arousal. We examined sexual arousal patterns among bisexual men recruited using stringent criteria designed to exclude those who were less likely to have sexual interest in both sexes. Furthermore, we included a bisexual stimulus depicting a man engaged in sex simultaneously with another man and a woman. On average, the bisexual men showed a bisexual arousal pattern, with respect to both self-reported and genital arousal. Additionally, the bisexual men were more aroused by the bisexual stimulus compared with the homosexual and heterosexual men. Some bisexual-identified men have bisexual genital arousal patterns, although it remains unclear how common they are.

Abstract
Studies of bisexual sexual interest have focused mostly on measures of genital arousal in bisexual men and have generally failed to find evidence of a bisexual pattern of genital arousal. Bisexual women have rarely been studied and other measures of sexual interest have not been used to study bisexual interest in either sex. In this study, we examined a non-genital measure of sexual interest, viewing time, among 16 bisexual men, 19 bisexual women, 15 heterosexual men, 15 heterosexual women, 15 homosexual men, and 10 homosexual women. Sexual orientation was determined from a self-report questionnaire. Stimuli were pictures of males and females of all five Tanner stages of sexual development. Participants were asked to rate the sexual appeal of the individuals depicted in the pictures, while the time taken to provide a response was covertly measured. Using a signed index that compared viewing times to pictures of sexually mature males and females, bisexual men and bisexual women did not look longer at pictures of one gender, whereas the other four groups had longer viewing times for pictures of one gender. Using an absolute index, the three groups of women showed a similar (and low) degree of gender preference. All groups showed longer viewing times for sexually mature individuals than for sexually immature individuals, suggesting that the viewing time responses of bisexual men and women were not produced by a general tendency to look indiscriminately at all pictures. There were small to moderate correlations between viewing times and rated sexual appeal in all groups. Results suggest that viewing time can be used to detect a bisexual pattern of sexual interest in bisexual men and bisexual women.

Abstract
A sample of 1,784 individuals responded to an online survey advertised on the Facebook social networking website. We explored the sexual orientation continuum by focusing on three components: self-reported sexual orientation identity, sexual attraction, and sexual partners. Results supported a 5-category classification of identity (heterosexual, mostly heterosexual, bisexual, mostly gay/lesbian, gay/lesbian) in that two added identity labels (mostly heterosexual and mostly gay/lesbian) were frequently chosen by participants and/or showed unique patterns of attraction and partners, distinct from their adjacent identities (heterosexual and bisexual, and bisexual and gay/lesbian, respectively). Those who reported an exclusive label (heterosexual, gay/lesbian) were not necessarily exclusive in other components; a significant minority of heterosexuals and the majority of gays/lesbians reported some attraction and/or partners toward their nonpreferred sex. The five identity groups differed in attraction and partners in a manner consistent with a continuous, rather than a categorical, distribution of sexual orientation. Findings also supported a sexual orientation continuum as consisting of two, rather than one, distinct dimensions (same- and other-sex sexuality). Having more same-sex sexuality did not necessarily imply having less other-sex sexuality, and vice versa. More men than women were at the exclusive ends of the continuum; however, men were not bimodally distributed in that a significant minority reported nonexclusivity in their sexuality.
