Transactional Sex, Substance Use, and Sexual Risk: Comparing Pay Direction for an Internet-Based US Sample of Men Who Have Sex with Men

Demographic, behavioral, and structural factors among four mutually exclusive transactional sex categories were assessed in an online sample of 7217 sexually active US men who have sex with men (MSM): (1) No Trade Sex group (87%); (2) Sellers, accepting money or drugs for sex (5%); (3) Buyers, giving money or drugs for sex (6%); and (4) Sellers and Buyers, accepting and giving money or drugs for sex (2%). Separate multivariable logistic regressions compared men who did not report past 60-day transactional sex with men in the three transactional sex groups. Sellers were more likely to report being black or Asian (versus white), low income, a recent STI diagnosis, six or more recent male anal sex partners, and polydrug use. Buyers were more likely to report being older, higher income, urban residence, incarceration history, a recent STI diagnosis, and having non-main sex partners. Sellers and Buyers were more likely to report a higher income, incarceration history, six or more recent male anal sex partners, and polydrug use. Findings suggest that public health policy and HIV prevention harm reduction strategies should address the distinct sexual and behavioral risk patterns among MSM who engage in transactional sex based on payment direction.
