This study analyzed event-level partnership data from a computer-assisted survey of gay and bisexual men GBM enrolled in the Momentum Health Study to delineate potential linkages between anal sex roles and the so-called " sex drugs," i.
Data for survey respondents and their sexual partners allowed testing these hypotheses for both anal sex partners in the same encounter. Multivariable results supported the first three hypotheses. Crystal methamphetamine was significantly associated with all anal sex roles in the univariable models, but not significant in any multivariable ones. Other multivariable significant variables included attending group sex events , venue where first met, and self-described sexual orientation.
Results indicate that GBM sex -drug use behavior features rational decision-making strategies linked to anal sex roles. They also suggest that more research on anal sex roles, particularly versatility, is needed, and that sexual behavior research can benefit from partnership analysis.
Despite the high HIV incidence and prevalence among black men who have sex with men BMSM , little research has examined partner characteristics, partner seeking venue, sexual position, substance use, and sexual risk behavior at the sex event-level among BMSM.
Using the baseline data from a multi-site study of BMSM stratified by their HIV status, the goal of this study was to conduct a detailed event-level analysis of male anal sex events to assess the factors associated with condomless anal intercourse CLAI with a HIV-discordant or HIV status-unknown partner. These results underscore the importance of delineating unique sex event-level factors associated with sexual risk behavior depending on individuals' HIV status.
