Depictions of visual sexual stimuli are changing with the advent of computer-generated imagery (CGI), hyper-realistic and idealized images created by artificial Intelligence (AI), and artistic styles such as hentai, that depict a diverse range of sexual situations and characteristics. Here we assessed the subjective realism, aesthetic value, subjective sexual attractiveness, and valence (pleasantness) of images depicting natural or surgically enhanced naked women taken from real photographs or in formats created by CGI, AI, or as dolls or hentai. Self-identified gynephilic males and females (N = 649) participated in a nationwide online survey about the perception of visual sexual stimuli. Although the real and AI-generated nudes were rated as significantly more realistic than the other categories, with the real images rated significantly more real than the others, AI-generated nudes were found more aesthetically appealing, sexually attractive, and pleasant than the other categories, with men rating nearly all categories higher than women (men and women found AI and CGI images equally aesthetically pleasing). There was a significant correlation of age, such that older participants found the real and AI-generated nudes more aesthetically appealing, sexually attractive, and pleasant than younger participants. In contrast, younger participants rated hentai significantly higher in these measures than older participants. These data suggest that AI-generated erotic material is superior to even real photographs in generating aesthetic appeal, positive valence, and ratings of sexual attractiveness, although both real and AI-generated nudes produced higher ratings in all measures compared to enhanced nudes, or those created by CGI, or as dolls or hentai.

Research on whether asexual individuals desire (romantic) relationships and, if so, how they picture their ideal relationship has been growing in the past few years. However, less is known about the preferred attributes of an ideal partner in such relationships and whether these partner(ship) preferences are different from what heterosexual individuals want. The goal of the present study was to compare the types of preferred relationships and the ideal characteristics of a long-term partner of self-identified asexual and heterosexual women. Additionally, we examined differences in characteristics of asexual and heterosexual women using self-evaluations of the same attributes used for the partner preference ratings. We used data from the Ideal Partner Survey, a large-scale, multinational online study. Of 51,775 participants, 51,328 identified as heterosexual (M_age = 25.13 years) and 447 identified as asexual (M_age = 24.03 years). To create comparable samples for analyses, each asexual person was matched with a heterosexual person using propensity score matching (relationship options sample = 646, partner preference sample = 780, self-rating sample = 772). Compared to heterosexual women, asexual women were less interested in purely sexual relationships and more interested in emotionally romantic and alternative types of committed relationships as well as not being in any relationship ("single"). Asexual women placed less importance on all partner preference attributes, except educated and intelligent. They also consistently rated themselves lower on all attributes than heterosexual women. These findings suggest distinct differences between asexual and heterosexual women in their relationship interests, partner preferences, and self-perceived characteristics.

The surge in pandemic uncertainty has fueled a rise in LGBTQ+ crimes as societal anxieties and existing prejudices have intensified. As global crises unfold, marginalized communities like LGBTQ+ individuals become increasingly vulnerable to targeted violence, reflecting deep-seated societal tensions. This research explored the impact of pandemic uncertainty on LGBTQ+ crimes across ten selected economies (Bangladesh, Brazil, Egypt, India, Indonesia, Kenya, Malaysia, Nigeria, Pakistan, and Russia). Unlike traditional methods that may overlook country-specific differences in panel data analysis, this research employs the quantile-on-quantile approach, which evaluates relationships between variables within the context of individual countries. This method enhances the precision of the findings and offers valuable insights into the unique characteristics of different economies. Unlike earlier studies that focused on a single variable, such as COVID-19, this research employs a comprehensive pandemic uncertainty index that integrates data from multiple pandemics, including SARS, MERS, avian flu, Ebola, and others. The findings uncover that pandemic uncertainty drives a surge in LGBTQ+ crimes across most of the examined countries, each displaying distinct patterns and trends. These insights underscore the urgent need for policymakers to conduct thorough assessments and craft targeted strategies that address the evolving impact of uncertainty on violence against LGBTQ+ individuals.

Research has highlighted the important role that communities of kink play in the social and sexual lives of kinksters. Existing literature has not examined the experience of community for rural and remote-living kink-identified individuals, where access to communities, networks of playmates, and spaces for kink may be limited by virtue of social and geographic isolation. The aim of this study was to explore the lived experience of community among self-identified cisgender gay men who engage in fist-fucking and live in rural areas. A qualitative study was conducted with a multi-national sample of 40 fist-fuckers, each of whom participated in an online semi-structured individual interview. Guided by a interpretative phenomenological analysis of the data, six themes were developed: (1) the experience of isolation in the formative journey of self-discovery; (2) geographic, logistical, and financial burdens in accessing community; (3) feelings of (dis)connection from the community and the struggle for kink identity; (4) the absence of community networks and resources in supporting healthcare needs; (5) the opportunities and challenges of online communities and connections; and (6) the lack of communal spaces and local networks of partners in fostering sexual satisfaction. The findings revealed that participants shared lived experiences of personal isolation, sexual frustration, and social exclusion from urban-based fisting communities. For some fist-fuckers, their rural-living circumstances produced not only social and sexual dislocations from their communities but, also, a disconnectedness from their kink identity. For others, the remoteness of their living contexts forged new modes of online community building, strategies for sexual and erotic resilience, and experiences of community.

Sexually transmitted infections (STIs) caused by HIV, Treponema pallidum (syphilis), and herpes simplex virus type-2 (HSV-2) are interrelated. Due to a mosaic of political, social, and economic situations, migrants are susceptible to acquiring STIs. The objective of this study was to estimate the seroprevalence of HIV, syphilis, and HSV-2 in migrants in transit in Tapachula, Chiapas, Mexico and to analyze their associated factors. A cross-sectional study was conducted between 2021 and 2022 in migrant care centers in the city of Tapachula, Chiapas, Mexico. A behavioral questionnaire was administered and a blood sample was collected. Immunological tests were performed to detect HIV, syphilis, and HSV-2. Associated factors were determined through multivariate binary logistic regression models. A total of 655 migrants participated, of which 51.5% were males. The seroprevalence of HIV, syphilis, and HSV-2 was estimated to be 8.9%, 10.5%, and 33.3%, respectively; for HIV and syphilis, the seroprevalence was higher among males than among females (p < 0.05), especially among men who have sex with men (MSM) and transgender women. A previous history of STIs, genital lesions, age at sexual debut, years of sexual activity, and having sex with members of the same sex were associated factors. In key groups, such as MSM and transgender women, the social and environmental contexts to which they are exposed as migrants, in interaction with clinical and behavioral factors, act as cumulative layers of vulnerability that increase the odds of migrants in transit to acquiring HIV, syphilis or HSV-2.
