There is increasing interest in the interpersonal factors that shape the development of asexual individual’s sexual identity, including age, gender, and romantic orientation. In this study, we examined variability in timing and pacing of asexual identity development milestones, with a focus on the diversity present in the asexual population. Among a sample of 317 participants aged 18–59 from three distinct birth cohorts, we measured participants’ ages of asexual identity development milestones, including: first awareness of a lack of sexual attraction, first searching for orientation, first discovery of the term asexuality, first self-identification, and first disclosure. Participants from more recent cohorts reported earlier and accelerated pacing of milestones relative to those from middle and older cohorts. Subgroups defined by gender also varied in milestone timing, with cisgender participants experiencing asexual identity development milestones at a later age than gender non-binary cohorts. No significant difference in milestones were found among romantic orientation sub-groups, apart from the timing of identity disclosure. Romantic-identified asexual individuals disclosed their asexual identities much sooner than aromantic-identified asexual individuals following identification as asexual. By comparing differences within subpopulations, the results of this study extend upon our understanding of the various sub-identities that exist within the asexual population and attend to different experiences within the asexual community. This in turn contributes towards our understanding of how asexual people experience interpersonal relationships, their interactions with others, and how they develop a positive sense of identity.

Based on in-depth interviews with 40 men involved in the Chinese sex industry, this study compared how engagement in sex work impacts, whether positively or negatively, the career development and transition to adulthood of middle-class and lower-class emerging adults. Most middle-class sex workers had concrete career goals outside of the sex industry and were on track to achieve those goals using their educational credentials and social and cultural capital. In contrast, most lower-class male sex workers relied on the lucrative nature of sex work to accumulate capital for their long-term goals, such as starting small businesses. Lower-class sex workers without career goals often spent their income on addictive habits, such as video games, and their engagement in sex work was not conducive to their long-term career development. Extending the literature on emerging adulthood to the context of sex work, I argue that for emerging adults who engage in sex work consciously with career goals, sex work could be viewed as a form of job exploration, while for those who engage in sex work without clear career goals, their engagement could be better described as floundering.

This study examined the association between self-identification as a sex worker (SW) and perceived access to pharmacologic and non-pharmacologic HIV prevention methods among MSM in France, Russia, and Türkiye amidst the COVID-19 pandemic. Globally, 17,250 MSM recruited through a geosocial networking smartphone application completed the COVID-19 disparities survey, which was administered between October and November 2020. Approximately 38% of survey respondents were identified as living in France (n = 1269), Russia (n = 3882), and Türkiye (n = 3141) at the time of survey completion. Given the diverse sociodemographic factors and attitudes toward both MSM behavior and commercial sex work in these countries, we conducted a secondary analysis of survey data exploring the relationship between SW status and perceived access to pharmacologic and non-pharmacologic HIV prevention methods during the COVID-19 pandemic. Among respondents in Russia and France, MSM SW status was associated with a reduction in perceived access to condoms/lubricants (p = .001 in Russia, p < .001 in France). MSM SW in France were less likely to report never using PrEP as compared to non-SW peers (RR = 0.40, p = .005). Our findings highlight the disparities in access to HIV prevention for MSM SW living in these three countries during the COVID-19 pandemic. Based on our findings, COVID-19 may have exacerbated pre-existing inequities in HIV prevention among populations experiencing intersecting stigmas.

Previous research suggests that human males, like males of many mammalian and avian species, adjust their ejaculate quality in accordance with sperm competition risk. Men who spend less time with their regular female partner since the couple's last copulation produce ejaculates with more sperm at the couple's next copulation (Baker & Bellis, 1993). We conducted a conceptual replication of this research to investigate whether sperm competition risk predicts ejaculate adjustment in human males using additional measures of sperm competition risk (e.g., perceptions of partner infidelity, presence of potential sexual rivals) and updated laser-optic semen analysis technology. We collected data from 34 heterosexual couples (age range 18-32 years) from a university population who completed self-report surveys on their relationship dynamics and provided six ejaculate samples (three copulatory and three masturbatory) across a 45-day period. Time spent together since the couple's last copulation was not significantly associated with ejaculate quality. However, sperm concentration for copulatory ejaculates was higher for men who perceived more potential sexual rivals. Discussion situates the current results within the literature on human sperm competition and suggests several directions for future research.

Male sexual functioning is a prerequisite for conception and consequently for reproduction and is thus a crucial mechanism from an evolutionary and social perspective. Previous studies reported better sexual functioning in coupled compared to single individuals. However, it is not clear whether sexual functioning increases or decreases with a short-term casual sexual strategy, which is another possibility, along with a long-term strategy. Furthermore, sexual orientation may represent yet another mating strategy that may influence sexual functioning. Here, we aimed to test the possible associations between male sexual functioning and sexual strategies, as measured through sociosexuality, relationship status, and sexual orientation. We hypothesize that due to its relationship with the evolved motivation of mate acquisition and mate retention, both stable relationships and sociosexuality would be positively associated with male sexual functioning. We did not expect significant differences in sexual functioning among men with different sexual orientations. We sampled 427 healthy men of different sexual orientations (203 heterosexuals, 77 bisexuals, and 147 gay men) who completed the Male Sexual Function Index (MSFI) and its subscales of desire, arousal, erection, orgasm, and satisfaction; the Sociosexual Orientation Inventory-Revised; and sociodemographic questions. A multivariate general linear model showed that, compared to single individuals, partnered individuals reported greater MSFI-arousal, MSFI-erection, MSFI-orgasm, and MSFI-satisfaction. Sociosexuality and sexual orientation only weakly predicted MSFI domains. Male sexual functioning thus seems to be moderately associated with a long-term mating strategy and can thus serve for relationship maintenance rather than for acquiring new partners.

The aim of this review was to investigate the mental and physical health outcomes of intimate partner violence (IPV) victimization among sexual and gender minority (SGM) individuals. This study addressed an existing gap in research concerning IPV outcomes among SGM populations. A systematic review was conducted through PubMed, APA PsycInfo, APA PsycNet, and manual searches on Google Scholar using specific keywords. Inclusion criteria included peer-reviewed publications and quantitative studies specifically assessing the impacts of IPV among SGM individuals. A total of 35 studies meeting these criteria were included in the review. Our review showed significant associations between IPV victimization and adverse mental and physical health outcomes, including posttraumatic stress disorder, depression, anxiety, suicidal ideation and attempts, substance use, and risky sexual behaviors among SGM individuals. IPV victimization poses mental and physical health risks for SGM populations. Our findings highlight the need for comprehensive, tailored intervention and prevention efforts that consider the diverse needs of individuals with multiple minoritized identities in the context of IPV victimization.

Young adulthood is a critical development period when mental health problems such as anxiety and depression become more prevalent. Likewise, there is evidence to suggest that depression and anxiety may lead to increased pornography usage. We examined the association of depression and anxiety symptoms with pornography viewing frequency among a prospective cohort of young adults (n = 1864) from California. Multinomial logistic regression models estimated the association of depression symptoms only, anxiety symptoms only, and comorbid depression and anxiety with pornography viewing frequency (never, < 3 times/month, one to several times/week, one to several times/day) at a 6-month follow-up. Models adjusted for gender, sexual orientation, sexual satisfaction, and adverse childhood experiences. Participants with comorbid depression and anxiety (vs. no depression or anxiety symptoms) had 2.72 (95% CI: 1.66-4.46) times the odds of frequent pornography viewing (one to several times/day) compared to never watching pornography. There was an association of depression symptoms only with frequent pornography viewing but it did not reach statistical significance (OR: 1.95, 95% CI: 0.78-4.89). Anxiety symptoms alone (vs. no depression and anxiety symptoms) were not associated with pornography viewing at any frequency in the full sample. However, in gender-stratified models, anxiety symptoms alone were associated with pornography viewing among women (OR: 1.44. 95% CI: 1.00-2.07), but not men (1.12, 95% CI: 0.65-1.96). Findings suggest comorbid depression and anxiety symptoms are associated with frequent pornography viewing among young adults, and anxiety symptoms alone are associated with pornography viewing among women, but not men.

Transgender and gender diverse (TGD) individuals represent a population with a heavy burden of HIV. Multi-level stigma encountered by TGD individuals can create significant barriers to discussing topics related to HIV prevention; however, research on communication between TGD patients and primary care providers (PCPs) about HIV vulnerability and prevention remains limited. This study used in-depth qualitative interviews with 25 TGD patients and 15 PCPs conducted in 2022 to explore perspectives on HIV vulnerability communication during primary care encounters. Overall, 14 of the TGD patients were nonbinary, genderqueer, or another gender identity; all but two participants identified as a sexual minority. The majority of PCPs (n = 11) were physicians. The range of years practicing medicine was between two and 39 years. Thematic analysis was used to organize codes and establish themes. Three broad themes regarding factors that facilitate communication regarding HIV vulnerability were identified: (1) focusing on behaviors over identities, (2) conveying impartiality, and (3) acknowledging individuality among TGD patients. Findings corroborate earlier research that identified strengths in providers refraining from behavior-based assumptions tied to a patient’s gender identity and sexual orientation and conveying impartial and nonjudgmental attitudes when discussing behaviors that can increase HIV vulnerability. Additionally, these findings underscore the significance of recognizing that, within the TGD community, all persons have unique circumstances, preferences, and needs. Future work should continue to explore the dynamics of HIV vulnerability and prevention discussions, especially among TGD individuals from diverse backgrounds and regions, to identify strategies for strengthening patient–provider communication and reducing vulnerability to HIV.
