Adult webcam sites with live performers who provide viewer interactive experiences are a rapidly increasing form of sexual entertainment or "sextech." The opportunity to engage with performers during synchronous contact without health risks represents a novel form of transactional sex. This study sought to understand viewer preferences in performers, and how viewers perceive webcam use is affecting their sex lives and their mood. Participants (N = 10,570) responded to a link on the adult webcam platform Chaturbate.com and completed a 93-item survey. Simple frequencies and descriptive statistics were used to characterize responses. Most viewers identified as heterosexual (75.1%) men (94.2%). Two-fifths (40.3%) had no sexual partners over the past 12 months. Exploratory factor analysis showed that respondents' preferred qualities in performers clustered around an ideal sexual partner, an emotional connection, power dynamics, and compliance with viewers' wishes. Respondents generally agreed that webcam use made them better educated about sex (66.0%) and feel better about their sex lives (54.6%), though about one-fourth reported less positive experiences. The majority (72.2%) felt watching cams was less satisfying than sex away from screen and only 19.1% defined watching cams as "real sex." Over half (64.0%) perceived their webcam use as having positive effects on their mood, while a moderate proportion perceived negative emotional consequences. Findings suggest that a majority of viewers experience their webcam activities as a means of obtaining sexual release, but that this is not considered actual sex. Future research should explore additional consequences of long-term use of transactional webcam sex.
