Modeling US blood donor deferrals under a policy of individual risk assessment for HIV risk sexual behavior.

BACKGROUND: In May 2023, the Food and Drug Administration (FDA) released final guidance for blood donor eligibility that recommended the elimination of 3-month deferral for men who have sex with men (MSM) and the related deferral for women who have sex with MSM. In its place, FDA introduced an individual risk assessment policy of asking all presenting blood donors, regardless of sex or gender, if they have had a new partner or more than one sexual partner in the last 3 months and deferring those who also report anal sex (penile-anal intercourse) during this period. We modeled the possible impact of this policy on the US blood donor base. STUDY DESIGN AND METHODS: We developed a computational model to estimate the percentage of blood donors who would be deferred under a policy of individual HIV risk assessment. The model incorporated demographic information about donors and national survey data on HIV risk behaviors and included age and sex distributions and dependencies. RESULTS: Our model estimates that approximately 1.2% of US blood donors would be deferred under the individual HIV risk assessment paradigm. DISCUSSION: The model predicts a relatively minor effect of replacing the time-based deferral for MSM with individual risk-based deferral for sexual behavior. As US blood centers implement this new policy, the effect may be mitigated by donor gains, which warrant further study. The new policy is unlikely to adversely affect the availability of blood and blood components.

Erectile dysfunction prevalence in the United States: report from the 2021 National Survey of Sexual Wellbeing.

BACKGROUND: There has been a great deal of public speculation regarding a surge in erectile dysfunction (ED) in younger men despite data consistently indicating that the ED prevalence rates increase with age. AIM: In this study we sought to assess the prevalence and risk of experiencing ED in a nationally representative sample of men in the United States across various social groups, describe comorbidities, and examine barriers to treatment. METHODS: Data from the 2021 National Survey of Sexual Wellbeing were analyzed by utilizing the Ipsos KnowledgePanel®, a probability-based online panel, for the purpose of obtaining US nationally representative data of adults aged 18 years and older. The analytic sample consisted of 1822 cisgender men ranging in age from 18 to 87 years, with a mean age of 47.5 years. OUTCOMES: Study outcomes were ED as measured by the 5-item version of the International Index of Erectile Function (IIEF-5), as well as self-reported diagnosis by a medical professional, comorbidities with other health issues, medications taken for ED, and barriers to treatment. RESULTS: The ED prevalence rate based on IIEF-5 scores was 24.2%. Prevalence increased with age: 52.2% of the 75+ age group, and 48.0% of the 65-74 age group meeting diagnostic criteria for ED. Diagnostic criteria were met for more participants in the 18-24 age group (17.9%) than the 25-34 (13.3%) or 35-44 (12.7%) age groups, but less than the 45-54 (25.3%) or 55-64 (33.9%) age groups. Only 7.7% (n = 141) of the sample reported having been diagnosed by a provider (n = 4 in 25-34, n = 6 in 35-44, n = 13 in 45-54, n = 39 in 55-64, n = 44 in 65-74, and n = 34 in ≥75-year olds), indicating a gap in access to treatment. The most common reason selected for not accessing care for ED concerns was a lack of need to see a provider in the past year. CLINICAL IMPLICATIONS: The discrepancy between ED self-report and medical diagnosis is critical, given that ED can be an indication of underlying health risks. STRENGTHS AND LIMITATIONS: This study is the first nationally representative update to information regarding the prevalence of ED in almost 2 decades. Standard administration of the IIEF-5 is limited to participants who have had sex in the last 6 months, so these rates do not include those men with ED who have been avoiding penetrative sex for a significant time. CONCLUSION: The results indicate that ED prevalence and severity remain highest in older age groups and that most individuals who meet criteria for ED have not sought medical care related to this concern.

Variations in Pre-exposure Prophylaxis (PrEP) Awareness and Healthcare Provider Interactions in a Nationally Representative Sample of American Men Aged 15-49 Years: A Cross-Sectional Study.

Awareness of and discussions with a healthcare provider (HCP) around pre-exposure prophylaxis (PrEP), an effective HIV prevention method, are associated with PrEP uptake, yet few studies utilize representative samples or report on these outcomes using distinct behavioral risk subgroups. This cross-sectional study utilized responses given by men on the 2017-2019 National Survey of Family Growth, a nationally representative survey of Americans aged 15-49 years. Multiple logistic regression models were used to determine how respondents' sociodemographic characteristics and HIV risk behaviors were related to PrEP awareness and HCP discussions. PrEP awareness was low (29.40%) as was the proportion who reported ever discussing PrEP with an HCP (4.48%). Odds of being PrEP aware and discussing PrEP with an HCP varied significantly within sexual behavior subgroups based on sociodemographic and behavioral characteristics highlighting the differential risks within distinct behavioral subgroupings of men. Sexual behavior subgroupings should be considered when promoting PrEP awareness and discussions as HIV risk behaviors vary considerably and sexual identity alone may not sufficiently capture one's HIV risk.

The lived experiences of rural HIV social workers.

HIV service providers are the primary implementers of HIV care services, but rural HIV service providers are under researched. We used an interpretative phenomenological analysis to explore rural HIV service providers' lived experiences of working in HIV care, who work in a rural region of a Midwestern state in the United States. From July to August 2019, 15 HIV service providers participated in a one-hour semi-structured telephone interview that elicited their experiences working in the rural HIV care continuum. Participants were tired of constantly educating and working to reduce HIV stigma; however, they received support from family and friends once they educated them about HIV. Participants felt they lacked control over systems and they developed emotional-based coping to address constant occupational stressors. Findings highlight the importance of resiliency and advocacy research and practice across ecological levels.

Sexual Repertoire, Duration of Partnered Sex, Sexual Pleasure, and Orgasm: Findings from a US Nationally Representative Survey of Adults.

In a confidential U.S. nationally representative survey of 2,525 adults (1300 women, 1225 men), we examined participants' event-level sexual behaviors, predictors of pleasure and orgasm, and perceived actual and ideal duration of sex, by gender and age. Event-level kissing, cuddling, vaginal intercourse, and oral sex were prevalent. Sexual choking was more prevalent among adults under 40. While women and men reported a similar actual duration of sex, men reported a longer ideal duration. Participants with same-sex partners reported a longer ideal duration than those with other-sex partners. Finally, findings show that gendered sexual inequities related to pleasure and orgasm persist.

"Don't Just Randomly Grab Someone's Neck during Intercourse!" An Analysis of Internet Articles about Choking/Strangulation during Sex.

Sexual choking/strangulation has become prevalent among young U.S. adults, yet little is known about media articles that teach readers about choking. We conducted a content analysis of 27 Internet articles, examining how choking is described, information related to health risks and healthcare, and article accuracy. Most articles described choking in positive terms and indicated choking can be done safely or properly, even while acknowledging potential dangers. Only two articles indicated having undergone expert/medical review. Few gave information about signs that would warrant seeking healthcare. Sexuality professionals need to be aware of choking-related information and misinformation in online media articles.

Masturbation Prevalence, Frequency, Reasons, and Associations with Partnered Sex in the Midst of the COVID-19 Pandemic: Findings from a U.S. Nationally Representative Survey.

Despite well-documented individual, relational, and health benefits, masturbation has been stigmatized and is understudied compared to partnered sex. In a US nationally representative survey of adults, we aimed to: (1) assess the prevalence and frequency of participants' prior-year masturbation, (2) describe reasons people give for not masturbating, (3) describe reasons people give for masturbating, and (4) examine the association between masturbation frequency and actual/desired partnered sex frequency in the prior year. Significantly more men than women reported lifetime masturbation, past month masturbation, and greater masturbation frequency. The most frequently endorsed reasons for masturbating related to pleasure, feeling "horny," stress relief, and relaxation. The most frequently endorsed reasons for not masturbating were lack of interest, being in a committed relationship, conflict with morals or values, or being against one's religion. Among women, those who desired partnered sex much more often and a little more often were 3.89 times (95% CI: 2.98, 5.08) and 2.07 times (95% CI: 1.63, 2.62), respectively, more likely to report higher frequencies of past-year masturbation than those who desired no change in their partnered sex frequency. Among men, those who desired partnered sex much more often and a little more often were 4.40 times (95% CI: 3.41, 5.68) and 2.37 times (95% CI: 1.84, 3.06), respectively, more likely to report higher frequencies of past-year masturbation activity than those who reported that they desired no change in their current partnered sex frequency. Findings provide contemporary U.S. population-level data on patterns of adult masturbation.

The Impact of Household Context on Self-Perceived Changes in Solo and Partnered Sexual Behaviors During the COVID-19 Pandemic: Findings from a U.S. Probability Survey.

To understand how household context factors impacted self-reported changes in solo and sexual behaviors in U.S. adults during early stages of the COVID- 19 pandemic, we conducted an online, nationally representative, cross-sectional survey of U.S. adults (N = 1010; aged 18-94 years; 62% response rate) from April 10-20, 2020. We used weighted descriptive statistics with Wilcoxon rank sign tests to understand the population prevalence and significance of self-reported changes (five-point scale: much less to much more) in 10 solo and partnered sexual behaviors. Ordinal regression was used to assess the impact of household predictor variables-including number of children at home, number of adults in home, partnership status (unpartnered, partnered and not living together, partnered and living together) and employment status (not working, employed not as essential worker, employed as essential worker). All models were adjusted for gender, age, sexual orientation, race/ethnicity, and residence location (urban, suburban, rural).All solo and partnered sexual behaviors showed some amount of significant change-increased activity for some and decreased for others-for U.S. adults during the pandemic. Not living with a partner was broadly associated with decreased affectionate partnered sexual behaviors; unpartnered adults reported increased sexting. Individuals not employed reported increased oral sex and increased consumption of sexually explicit materials as compared to non-essential workers. Number of children at home and household size were not significantly linked to self-reported behavior change. Ongoing sexual health-focused research should continue to focus on understanding how adults manage opportunities and constraints to their sexual lives in the context of a still-going pandemic. While many aspects of social life look more "normal" (e.g., many people have returned to their in-person offices and children are largely back in school), new and more-infectious strains of COVID-19 have proven that the pandemic may still yet impact daily living. Lessons learned from COVID need to include sexual health planning both for any future strains of COVID, as well as for future public health emergencies.

U.S. Parents Underestimate Their Children's Pornography Use and Learning.

Research on parental knowledge and positive adolescent adjustment suggests that more accurate levels of the former increase the likelihood of the latter. Despite a significant body of literature correlating adolescent pornography use with negative adolescent adjustment, however, only a handful of studies have compared parents' beliefs about their children's pornography use with adolescents' reports and just a few of these have been carried out in the U.S. The present study employed national probability data gathered from 614 parent-adolescent dyads in the U.S. as a further step toward bolstering this important area of parent-child research. Parents were 44.78 years old on average (SD = 7.76). Mothers comprised 55.80% of parents (fathers were 44.20%). Children were 15.97 years old on average (SD = 1.38). Daughters comprised 50.20% of children (sons were 49.80%). Boys were more likely to report pornography use and learning across a range of pornography genres and sexual domains. Parents accurately estimated the direction of many of these gender differences, but still consistently underestimated both sons' and daughters' exposure to and socialization from pornography. Interestingly, although parents were more likely to believe that sons than daughters had viewed and learned from pornography, their degree of underestimation was larger for sons. Mothers' and fathers' beliefs were consistently indistinguishable at the main effect level and interacted with child gender in only one instance. Results are discussed in relation to the moral panic and risk underestimation perspectives on youth and media effects.

#ChokeMeDaddy: A Content Analysis of Memes Related to Choking/Strangulation During Sex.

Recent research indicates that some young people initially learn about sexual choking through Internet memes. Thus, a qualitative content analysis was performed on 316 visual and textual memes collected from various social media websites and online searches to assess salient categories related to choking during sex. We identified nine main categories: communication, gendered dynamics, choking as dangerous, choking as sexy, sexualization of the nonsexual, shame and worry, romance/rough sex juxtaposition, choking and religious references, instructional/informational. Given that memes, through their humor, can make difficult topics more palatable and minimize potential harm in the phenomenon they depict, more concerted, synergistic effort that integrates media literacy into sexuality education programming on the potential risks that may ensue for those engaging in sexual choking is warranted.

Pornography Consumption and Sexual Choking: An Evaluation of Theoretical Mechanisms.

Many researchers interested In the socializing effects of pornography have found heuristic utility in the sexual script acquisition, activation, application model (3AM) of mediated sexual socialization. Studies have emphasized overall pornography/sexual behavior associations, however, rather than mediating sexual beliefs that a 3AM perspective suggests should underlie such associations. The present study used data from a campus-representative probability sample to examine whether linkages between pornography use and heterosexual-identified collegiate men's choking of sexual partners is mediated by the belief that sexual choking is pleasurable, the belief that sexual choking is safe, and the disbelief that sexual choking requires consent from the person being choked. Sexual choking has been increasingly identified as a focal point of contemporary mixed-sex pornography as well as young men's sexual behavior; it can also result in adverse health and legal consequences. Results were consistent with a sequential model positing that consuming pornography more frequently leads to more exposure to pornographic depictions of sexual choking, which in turn predicts a higher likelihood of choking sexual partners through the belief that sexual choking is pleasurable, the belief that sexual choking is safe, and the disbelief that sexual choking requires consent from the person being choked.

Perceived Similarity, Utility, and Social Realism as Potential Mediators of the Link between Pornography Use and Condomless Sex.

One of the most consistent findings in content analyses of popular, commonly consumed pornography is the near absence of condoms. A recent meta-analysis found that pornography use is associated with an increased likelihood of condomless sex, but the studies available for analysis rarely included measures of potential cognitive mediators underlying the association. Following the sexual script acquisition, activation, application model (3AM) of mediated sexual socialization and the differential susceptibility to media effects model (DSMM), the present study examined whether linkages between pornography use and condomless sex are mediated by perceived similarity to actors in pornography and heightened perceptions of pornography's utility and social realism. Social realism and similarity mediated the association between pornography consumption frequency and condomless sex in simple mediation models, but only social realism remained significant in a parallel process model inclusive of all three mediators.

Pornography, Sexual Insecurity, and Orgasm Difficulty.

While recent meta-analyses have provided answers to a number of historically contentious debates about correlates of pornography use, several questions remain unanswered. Whether pornography is associated with sexual functioning is one such question. Informed by theorizing on sexual scripting, social comparisons, and sexual objectification, the present study examined the possibility that pornography is related to orgasm difficulty through sexual insecurity (i.e., insecurity about one's sexual performance and sexual attractiveness). Data were from the National Survey of Porn Use, Relationships, and Sexual Socialization (NSPRSS), a U.S. population-based probability study. There was an indirect effect of pornography consumption frequency on orgasm difficulty through sexual insecurity. Participants who used pornography more frequently reported higher levels of sexual insecurity, and higher levels of sexual insecurity predicted orgasm difficulty. There was also an indirect effect of partner pressure to view pornography on orgasm difficulty. Higher levels of partner pressure to view pornography were associated with higher levels of sexual insecurity, which in turn predicted orgasm difficulty. Results were indistinguishable by gender and maintained after controlling for a number of potential confounds. These findings suggest that some men and women's personal and (pressured) partnered pornography consumption have the potential to increase orgasm difficulty through bodily and performance insecurity.

Skin Color and Skin Tone Diversity in Human Sexuality Textbook Anatomical Diagrams.

Little is known about skin tone and skin color representation within sexuality education materials. A content analysis was performed to assess skin tone and skin color diversity among anatomical images (n = 182) within eight contemporary, college-level human sexuality textbooks. Of these images, 1.1% represented dark skin tones while 83.5% represented light skin tones. Skin colors commonly associated with Black and Brown people were underrepresented in comparison to colors generally associated with white or white-presenting people such as conch, which comprised 42.3% (n = 77) of anatomical images. We encourage sex therapists to use racially conscious and inclusive imagery and educational materials when serving clients.

"If Their Face Starts Turning Purple, You Are Probably Doing Something Wrong": Young Men's Experiences with Choking During Sex.

Choking/strangulation during sex has become prevalent in the United States. Yet, no qualitative research has addressed men's choking experiences. Through interviews with 21 young adult men, we examined the language men use to refer to choking, how they first learned about it, their experiences with choking, and consent and safety practices. Men learned about choking during adolescence from pornography, partners, friends, and mainstream media. They engaged in choking to be kinky, adventurous, and to please partners. While many enjoyed or felt neutral about choking, others were reluctant to choke or be choked. Safety and verbal/non-verbal consent practices varied widely.

Meanings of Rough Sex across Gender, Sexual Identity, and Political Ideology: A Conditional Covariance Approach.

The purpose of this study was to investigate how various subgroups based on gender, sexual identity, and political ideology conceptualize rough sex. We used available data from a 2020 survey of randomly sampled undergraduate students at a large public university in the Midwestern U.S. (n = 4,989). The dichotomous responses to 13 items on the rough sex meaning scale were analyzed using a conditional covariance approach to better understand which behaviors commonly described as rough sex behaviors were prevalent. Our results showed that rough sex was conceptualized largely as a two-dimensional construct for vast majority of subgroups. Across all subgroups, nine of the 13 behaviors clustered along two dimensions in the same way. Specifically, four behaviors related to hair pulling, being pinned down, hard thrusting, and throwing someone onto a bed clustered together as one dimension (spanking and tearing clothes off being present along this dimension for vast majority of the subgroups). Being tied up, slapping, choking, punching, and making someone have sex behaviors formed a separate dimension of rough sex across all studied groups (with biting and scratching being associated with this dimension for vast majority of subgroups).

Non-Fatal Strangulation/Choking During Sex and Its Associations with Mental Health: Findings from an Undergraduate Probability Survey.

Choking/strangulation during sex is prevalent among young adults in the United States. We examined associations between having ever been choked and participants' current mental health symptoms (e.g., feeling depressed, anxious, sad, lonely) in the prior 30 days and in the prior year. Participants were 4352 randomly sampled undergraduates who completed a confidential online survey and reported lifetime partnered sexual activity. 33.6% of women and 6.0% of men reported having been choked more than five times. After adjusting for demographic characteristics, having been choked remained significantly associated with all four mental health outcomes, except for overwhelming anxiety among men.

Pornography and Relational Satisfaction: Exploring Potential Boundary Conditions.

Recent meta-analytic and other large-scale multi-sample studies have established that pornography use is generally associated with lower relational satisfaction. Nevertheless, much remains unknown about the potential boundary conditions of this relationship. Using data from a campus-representative probability sample of more than 750 graduate students in a committed romantic relationship, this exploratory study examined whether the association between more frequent pornography consumption and lower relational satisfaction was moderated by gender, sexual orientation, race, relational length, religious participation, and moral disapproval of pornography. The bivariate correlation between more frequent pornography use and lower relational satisfaction was small, but significant and replicative of prior meta-analytic results. Planned two-way interaction analysis indicated that this association was moderated by gender, with men, but not women, evidencing the negative association. None of the other potential moderators yielded significant two-way interactions. A supplementary three-way interaction analysis, however, suggested that the negative association between pornography consumption and relational satisfaction was primarily carried by White men. These results provide optimism for the replicability of previous findings on pornography and relational satisfaction and suggest that moderated models should incorporate race, in addition to gender, when predicting relational satisfaction from pornography use.

Changes in Penile-Vaginal Intercourse Frequency and Sexual Repertoire from 2009 to 2018: Findings from the National Survey of Sexual Health and Behavior.

Solo and partnered sexual behaviors are relevant to health, well-being, and relationships. Recent research shows that sexual frequency has declined in the U.S. and in other countries; however, measurement has been imprecise. We used data from 14- to 49-year-old participants in the 2009 and 2018 waves of the National Survey of Sexual Health and Behavior (NSSHB), a confidential U.S. nationally representative survey that is conducted online. We aimed to: (1) assess changes in frequency of past-year penile-vaginal intercourse and (2) examine combinations of past-year sexual behaviors for each of the two waves. We hypothesized that we would observe lower frequency of penile-vaginal intercourse (PVI) from 2009 to 2018 and that we would observe greater engagement in sexual repertoires involving non-coital partnered behaviors (e.g., partnered masturbation, oral sex) in 2018 as compared to 2009. Participants were 4155 individuals from the 2009 NSSHB (Adolescents: 406 females, 414 males; Adults: 1591 women, 1744 men) and 4547 individuals from the 2018 NSSHB (Adolescents: 416 females, 411 males; Adults: 2007 women, 1713 men). Compared to adult participants in the 2009 NSSHB, adults in the 2018 NSSHB were significantly more likely to report no PVI in the prior year (28% in 2018 vs. 24% in 2009). A similar difference in proportions reporting no PVI in the prior year was observed among 14-17-year-old adolescents (89% in 2018 vs. 79% in 2009). Additionally, for both adolescents and adults, we observed decreases in all modes of partnered sex queried and, for adolescents, decreases in solo masturbation.

Genital Self-Image, Sexual Function, and Quality of Life Among Individuals with Vulvar and Non-Vulvar Inflammatory Dermatoses.

Vulvar inflammatory dermatoses (VID; e.g., lichen sclerosus, lichen planus, vulvar dermatitis) can significantly impact sexual function. Both vulvar and non-vulvar inflammatory dermatoses (NVID; i.e., skin conditions not impacting vulvar skin, such as non-genital psoriasis and eczema/dermatitis) have yet to be fully characterized with regard to impact on genital self-image. A 20-min web-based survey was distributed September-November 2020 through social media ads, support groups, and online research recruitment services. Individuals in the USA over age 18 who were assigned female at birth and self-reported having been diagnosed with an inflammatory dermatosis were eligible. The primary outcome was the Female Genital Self-Image Scale (FGSIS). Secondary outcomes included the Female Sexual Function Index (FSFI), the Skindex-16 (a skin-related quality of life measure), the PROMIS Global-10 (assessing global physical/mental health), and sexual behavior histories. Participants (n = 348) reported mean age of 43.1 ± 15.5 (range = 19-81). Nearly one-third (n = 101; 29.0%) reported VID, 173 (50%) had NVID, and 74 (21%) experienced both vulvar and non-vulvar symptoms; they were analyzed as part of the VID group. The mean FGSIS score among participants with VID was 16.9 ± 4.1 and was significantly (p < .01) lower than that of participants with NVID (M = 21.2 ± 4.3), indicating lower genital self-image. Mental health (as measured by PROMIS-Global 10) was also impaired in VID. Rates of sexual dysfunction were high in both groups (> 60%). Findings suggest that in VID, lower genital self-image is correlated with poorer sexual function, quality of life, and global physical and mental health. Additional recommendations for VID management are proposed.
