Sexual Excitation and Sexual Inhibition in the Context of Sexual Risk-Taking

HIV Treatment Optimism Moderates the Relationship between Sexual Risk Behavior and HIV Risk Perception among Urban HIV-negative Gay, Bisexual, and Other Men who have Sex With Men

Using baseline data of the Engage Cohort Study, a Canadian study of sexually active gay, bisexual and other men who have sex with men (GBM), we evaluated the association between sexual behavior and risk perception among HIV-negative participants and whether HIV treatment optimism moderated this relationship. Participants were recruited by respondent-driven-sampling (RDS). We defined high-risk sexual behavior in the past six months as any condomless anal sex with a casual partner (i.e. not the participant's main partner) with either unknown HIV-status where neither used pre-exposure prophylaxis or with a partner living with HIV having detectable/unknown viral load. We assessed HIV treatment optimism-skepticism using a 12-item scale. RDS-II-weighted adjusted logistic regression models examined associations with risk perception measured by the question "How would you assess your current risk of getting HIV?" (response options were on a 6-point Likert-scale ranging from "very unlikely" to "very likely", dichotomized into "No Perceived Risk" (very unlikely/unlikely) and "Perceived Risk" (somewhat likely/likely/very likely/I think I already have HIV). Of 1961 participants, engagement in high-risk sexual behavior was reported by 155 (17.0%), 62 (12.4%), 128 (17.2%) of participants in Montréal, Toronto, and Vancouver, respectively. High-risk sexual behavior increased the odds of perceived HIV risk (pooled adjusted odds ratio = 2.9, 95%CI = 2.2-3.8). HIV treatment optimism-skepticism scores moderated the relationship: for GBM engaging in high-risk sexual behavior, higher HIV treatment optimism-skepticism scores increased perceived HIV risk. Promoting awareness around advances related to HIV prevention and treatment is important for appropriate risk assessment and for increased engagement in prevention interventions.

Condom Use Beliefs Differ According to Regulatory Focus: A Mixed-Methods Study in Portugal and Spain

Reports worldwide have been showing increasing rates of sexually transmitted infections (STIs) and condomless sex in recent years. Research has identified several individual and situational variables that can determine the decision to use condoms or forgo their use. We argue that such a decision can also be shaped by motives related to pleasure and safety (i.e., regulatory focus in sexuality). Using open ended questions, we asked 742 Portuguese and Spanish adults to indicate situations and reasons that could inform the decision making process with casual partners and the functions/attributes related to condoms. Using thematic analyses, we coded the drivers of condomless sex and condom use into themes and subthemes, and computed their frequencies. Using quantitative measures, we also asked participants to indicate their condom use expectancies and perceived barriers. Comparing participants according to regulatory focus revealed some differences. Pleasure promotion participants were more likely to consider that condom use decision making is driven by unexpectedness, pleasure, and intimacy pursuit, attached more pleasure reduction functions to condoms, expected more negative outcomes in condom use, and endorsed more sensation and partner barriers in condom use. In contrast, disease prevention participants were more likely to consider that condom use decision making is driven by adequate sexual education, responsibility, and behavioral control, and attached more health protective functions to condoms. These differences can inform the development of tailored intervention and awareness campaigns aimed at helping people to use condoms more consistently with casual partners and to avoid behaviors that put them at risk of STI transmission.

The Dual Control Model of Sexual Response: A Scoping Review, 2009-2022

The Dual Control Model proposes that sexual arousal and related processes are dependent on the balance between sexual excitation and sexual inhibition, and that individuals vary in their propensity for these processes. This scoping review provides an overview and discussion of the questionnaires used to measure the propensities for sexual excitation and inhibition, their translation and validation in other languages, and their application in empirical research on topics ranging from sexual desire and arousal, sexual (dys)function, sexual risk taking, asexuality, hypersexuality, and sexual aggression. A total of 152 papers, published between 2009 and 2022 and identified using online databases, were included in this review. The findings, consistent with those reviewed by Bancroft et al. (2009), suggest that sexual excitation is particularly relevant to sexual desire and responsivity and predictive of asexuality and hypersexuality. Sexual inhibition plays a role in sexual dysfunction. sexual risk taking, and sexual aggression, although often in interaction with sexual excitation. Suggestions for the further development of the model and for future studies are discussed.
