The Sexual Discounting Task (SDT) was developed to evaluate the effects of delay on decision making as it relates to sexual risk-taking behaviors. Though previously validated with other populations, including urban emerging adults, the current study sought to validate the SDT with adolescents. A sample of adolescents (N = 155; 61% female) between ages 14 and 21 (Mage  = 19.5 years) was recruited to complete the SDT (involving choices between immediate unprotected sex and delayed sex with a condom with hypothetical sexual partners) and the Delay Discounting Task (a delay discounting task for money outcomes)...

The mating effort questionnaire (MEQ) is a multi-dimensional self-report instrument that captures factors reflecting individual effort in upgrading from a current partner, investment in a current partner, and mate seeking when not romantically paired. In the current studies, we sought to revise the MEQ so that it distinguishes among two facets of mate seeking-mate locating and mate attracting-to enable a more nuanced measurement and understanding of individual mating effort. Moreover, we developed additional items to better measure partner investment...

One proposal for the persistence of homosexuality in the human population is the sexually antagonistic gene hypothesis, which suggests that the lower fertility of homosexual individuals, especially men, may be compensated by higher fertility of their relatives of the opposite sex. To test this hypothesis, we have collected data from 7,312 heterosexual men, 459 gay men, 3,352 heterosexual women, and 79 lesbian women mainly from Czechia. In an online survey, participants answered questions regarding their own as well as their parents' and grandparents' fertility...

Men who engage in transactional sex with men (MTSM) are a high-risk population for HIV and other sexually transmitted infections. Epidemiological data have so far included them in the broad category of men who have sex with men (MSM), while research on transactional sex typically focused on female sex workers. The internet has substantially changed sex work practices and earlier findings concerning the sexual health needs of MTSM may no longer be applicable. We analyzed quantitative data from MSM based in the UK (n = 11629) taking part in the European MSM Internet Survey (EMIS-2017)...

BDSM is a type of sexual preference that includes bondage and discipline, dominance and submission, and sadism and masochism. Research has identified three specific power exchange roles in the practice of BDSM: dominance, submission, and switch. It has also been suggested that attachment style potentially influences BDSM interests. This study investigated the potential roles of attachment style in driving BDSM identity. A questionnaire was completed by a cross-sectional Chinese sample (n = 3310, age range 18-30 years), including 1856 BDSM practitioners (436 men, 1420 women)...

Surrogate partner therapy is a type of treatment in which the surrogate partner (SP) works in a triadic setting with a sex therapist and a patient. At the same time, the SP acts as an intimate surrogate partner to the patient. The SP treatment includes a range of therapeutic experiences such as relaxation, intimate communication, sensual and sexual contact, and training for the acquisition of social skills. In the current study, we ask what and how SPs experience, understand, and construct boundaries in their work...

Two components of gender identity are gender similarity, how one's self-concept relates to the major gender collectives (i.e., female, male), and felt pressure to conform to gender norms. The development of these components across ages and contexts has been understudied. The focus of this study was to examine variations in gender similarity and felt pressure across multiple intersecting contexts: developmental stage, gender, and ethnic-racial group. Six data sets were harmonized and means were compared across 2628 participants (51% girls, 49% boys) from four different developmental cohorts (childhood n = 678, early adolescence n = 1322, adolescence n = 415, and young adulthood n = 213) from diverse ethnic-racial backgrounds (45% White, 23% Latinx/Hispanic, 11% Black/African-American, 7% Asian-American, 5% American Indian, and 5% Multiracial)...

Research on the biological determinants of male homosexual preference has long realized that the older brother effect (FBOE, i.e., a higher fraternal birth rank of homosexuals) and the antagonist effect (AE, i.e., more fertile women have a higher chance of having a homosexual son) can both generate family data where homosexual men have more siblings and more older siblings than heterosexual men. Various statistical approaches were proposed in the recent literature to evaluate whether the action of FBOE or AE could be discriminated from empirical data, by controlling for the other effect...

Existing research suggests a number of both costs and benefits to oneself that can occur as a result of partners' other relationships in consensual nonmonogamy (CNM), but such costs and benefits have not previously been systematically cataloged. Using reflexive thematic analysis, we present themes derived from semi-structured interviews with 51 individuals (63% white, 55% nonbinary/genderqueer/non-cisgendered, and 77% LGBQ) who have practiced CNM, describing the costs and benefits to themselves that they perceive as a result of their partners' other relationships...

Unhealthy alcohol use and sexually transmitted infections (STIs) are significant public health concerns for US college students. Because alcohol use and condomless sex often co-occur in this population, alcohol-associated condomless sex has been identified as a behavioral intervention target. Existing theoretical frameworks have not garnered sufficient empirical support to serve as the foundation for interventions. The primary goal of the current study was to use a mixed-methods approach to develop a model of college student alcohol-associated condomless sex that combines elements from well-established health behavior theories...

Penile inversion vaginoplasty (PIV) is a gender-affirming surgical procedure where the skin of the penis and scrotum is reconstructed into the neovaginal lining. To prevent hair-bearing skin from becoming incorporated into the neovaginal canal, transgender patients are encouraged to undergo hair removal of their external genitalia. The goal of this preoperative hair removal is to minimize the risk of potential hair-related complications after vaginoplasty. To better support patients seeking preoperative hair removal and identify current treatment barriers, we surveyed patients about their progress and satisfaction with hair removal...

The mechanisms underlying sexual orientation differences in psychopathology originating in childhood remain understudied since sexual orientation does not directly manifest in childhood. This study tested whether childhood gender nonconformity and parental maltreatment before age 6 years 9 months partly explained sexual orientation disparities in the developmental trajectories of emotional and behavioral difficulties from age 6 years 9 months to 11 years 8 months. The Avon Longitudinal Study of Parents and Children was used (2182 boys and 2422 girls, Mage = 15...

Adolescence is an important period for the development of gender identity. We studied the development of gender non-contentedness, i.e., unhappiness with being the gender aligned with one's sex, from early adolescence to young adulthood, and its association with self-concept, behavioral and emotional problems, and adult sexual orientation. Participants were 2772 adolescents (53% male) from the Tracking Adolescents' Individual Lives Survey population and clinical cohort. Data from six waves were included (ages 11-26)...

This article relies on quantitative data collected in Switzerland as part of a research study on sexual transactions among youth. Building on an analytical framework that defines sexual transactions in terms of negotiated exchanges rooted in social representations, we explored how they were perceived by the Swiss young people included in our sample at a cognitive, ethical, and political level. We found that research participants who reported having experienced sexual transactions viewed them much more positively than those who reported never having engaged in such exchanges...

Internationally, HIV-related stigma and crystal methamphetamine (meth) use have been described as barriers to treatment adherence among gay, bisexual, and other men who have sex with men (gbMSM). Crystal meth use has been increasing among gbMSM in the Metropolitan Area of Mexico City (MAMC). Therefore, this study aimed to determine the association between HIV-related stigma and HIV treatment adherence among gbMSM who use crystal meth in the MAMC. This study was undertaken as part of an exploratory study of crystal meth use in the MAMC...

Genital self-image (GSI) involves subjective perceptions, experiences, and feelings of individuals regarding their genitalia. A negative GSI contributes to lower sexual esteem and, consequently, negative sexual experiences and sexual dysfunction. In men, self-perception may be influenced by several factors, including penis size or shape, personal experiences, body image, general health status, sex education, and even the media they consume. This study aimed to understand the reasons that lead to dissatisfaction with GSI among Brazilian men...

Gender dysphoria and autism spectrum disorder (ASD) co-occur at high rates. Yet, it is unknown whether gender dysphoria and ASD are associated with common or distinct neurobiological correlates or how they relate to experiences of gender-related body incongruence. Using the Social Responsiveness Scale, we assessed autistic traits in 99 transgender and 99 cisgender individuals and investigated their associations with gender-related body incongruence, measured via a visually based "Body Morph" test, and with cortical thickness in the brain...

We introduce internalized heterosexist racism (IHR), or the internalization of damaging stereotypes, harmful beliefs, and negative attitudes about being a sexual minority person of color. We also present the initial development and validation of the Brief Internalized Heterosexist Racism Scale for gay and bisexual Black men (IHR-GBBM), a unidimensional, 10-item measure of IHR. Exploratory factor analyses on an internet-obtained sample of gay and bisexual Black men (N = 312; Mean age = 30...
