People with intellectual disability face a variety of epistemic injustices-systems of knowledge and educational inequality-related to their access to sex education and perceptions of their sexuality. Sex educators are in a position to address these injustices; however, they may not be fully aware of their own epistemic ethics. Furthermore, there is little theoretical understanding of how sex educators provide instruction within an environment that exhibits hostility toward the sexual expression of those with intellectual disability. This grounded theory study of interviews with 58 people who taught sex education to people with intellectual disability sought to understand the role of educators in perpetuating and resisting epistemic injustice by utilizing sex education to either facilitate or restrict the sexual expression of people with disabilities. We identified four micro-contexts: centralizing capacity to consent, emphasizing risk, desexualizing (through) sex education, and acknowledging gender identity. In each micro-context, we explore mechanisms of how educators were either allied in support of autonomy (person-centered values, expertise, access to curricular resources, self-advocates as teachers and partners, subversiveness, and de-problematizing normative sexual behavior) or reified sexual stigmas (fear of sexual abuse and sexual perpetration, conscripting to asexuality, the paternalistic service system, and complex ethical dilemmas) in the context of hostility to sex education and sexual expression. These findings have implications for promoting prosocial sexual expression and access to sex education for people with intellectual disability.

Previous research has shown that people’s thoughts, feelings, and behaviors can be embodied within their sensorimotor experiences. For example, people tend to associate “toughness” with males and “tenderness” with females in their spoken and mental metaphors. In the current research, we investigated the role of culture in this embodied categorization of gender, focusing specifically on the role of social system and organization. Based on sociological findings that highlight the dominance of men in patriarchy, we hypothesized that Geba, a primitive patriarchal tribe in southwest China, were more likely to use the sensory experience of toughness for representations of gender categories than matched groups of Kham Tibetans. Across two studies, both groups of participants who were primed with the proprioceptive experience of toughness were more prone to categorize sex-ambiguous faces as male (vs. female) than those who received sensory feedback about the relative tenderness, which replicated prior finding in Western participants. Notably, the embodied effect of toughness on categorical judgments of gender was more pronounced in Geba Tibetans than Kham Tibetans, which suggests that social system may be an important determinant of social–categorical thinking about gender. Taken together, these findings highlight the importance of cultural dynamic in accounting for embodied cognition.

Understanding the psychological conflicts associated with pornography consumption can help professionals tailor their interventions to address the mental health risks faced by individuals struggling with issues related to their pornography use. The main objective of this research was to investigate how pornography consumers are perceived from a social representation theoretical perspective and to examine variations in these perceptions—or social representations—according to gender, relationship satisfaction, and sexual satisfaction. All participants (N = 875 Romanians) were in a romantic relationship at the time of participation. Our results indicated that the social representation of pornography consumers varied significantly depending on gender, sexual satisfaction, and relationship satisfaction. Also, our findings showed a potential psychological conflict in the long run, which can put individuals at risk for self-stigma, guilt, and subsequent mental health consequences. We discuss conclusions from both a theoretical and practical perspective, with a focus on the utility of our conclusions in the clinical practice context of psychologists, psychotherapists, and mental health workers when dealing with issues related to pornography use.

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.
