Geosocial networking apps (GSN; e.g., Tinder, Grindr) have rapidly increased in popularity, showing associations with greater sexual risk-taking. This study sought to distinguish between risks associated with intensive partner-seeking (i.e., individuals seeking out casual sex frequently across many venues) and risks associated with specific venues (e.g., GSNs, dating websites, offline activities). Expanding upon a literature predominantly focused on the population of men who have sex with men (MSM), we recruited a broader range of sexual identities. A convenience sample of 3180 participants from the U.S. (18-75 years old, 69% female, 75% Caucasian, 68% heterosexual) completed an anonymous, cross-sectional online survey. Logistic regressions yielded adjusted odds ratios highlighting the unique links between each predictor and sexual risk-taking. MSM/WSW indicators, quantity of partner-seeking and specific venues-particularly GSN use-emerged as robust predictors of sexual risk, increasing the odds of reporting all six outcomes examined: (1) having three or more sex partners in the last year, (2) having hookups in the last 2 months, (3) having hookups involving alcohol or (4) drug use, (5) condomless sexual activity with new partners in the last 2 months, and (6) ever having had a sexually transmitted infection. Although a large portion of risk originated from the proclivities of the individuals seeking casual sex, both online and offline methods of partner-seeking also contributed significant risk, suggesting that specific venues like GSN apps could be used as methods of targeting higher-risk behaviors. The results also highlight the importance of moving beyond MSM when addressing sexual risk.
