Geosocial Networking Application Use, Characteristics of App-Met Sexual Partners, and Sexual Behavior Among Sexual and Gender Minority Adolescents Assigned Male at Birth.

Although many sexual and gender minorities (SGM) assigned male at birth (AMAB) use sexual networking applications intended for adult sexual minority men, little is known about adolescents' use of these technologies and characteristics of their online-met partners. We conducted an online survey of 219 sexually experienced SGM AMAB adolescents in the USA aged 15-17 (39.3% racial/ethnic minority; 74.9% gay; 94.1% cisgender male). Questions assessed app use patterns, partner-seeking behaviors on sexual minority male-specific apps vs. social media/other dating apps, app-met partner characteristics, and sexual behavior with app-met partners. Most (70.3%) used apps for sexual minority men, 14.6% used social media/other apps to meet partners, and 15.1% used neither. Nearly 60% of adolescents who used any type of app reported having met people from the apps in person, and nearly 90% of these reported at least one online-met sexual partner. Most partners were reportedly older than participants, and participants were more likely to report condomless receptive anal sex with older (vs. younger) online-met partners. Although partnerships were primarily sexual in nature, a minority reported friendships or serious partnerships. Meeting same-sex/gender partners via applications for adults may be common among SGM AMAB adolescents, which has implications for their sexual health and well-being.
