“…Although the prevalence of sexual fluidity in adults (i.e., ages 18+) is relatively well documented (e.g., studies assessing outcomes longitudinally, such as the General Social Survey; Scheitle & Wolf, 2018), longitudinal surveys in adolescence (i.e., ages 13-18) are rare. The AddHealth survey (Hu, Xu, & Tornello, 2016;Li, Pollitt, & Russell, 2016;Savin-Williams, Joyner, & Rieger, 2012;Savin-Williams & Ream, 2007), and the Growing Up Today Study (GUTS; Katz-Wise et al, 2017;Ott et al, 2011) found that fluidity of sexual orientation identity was higher among young women than men (Ott et al, 2011;Savin-Williams et al, 2012). A third study from New Zealand drawn from a birth cohort (aged 21 to 26 years) found that around 10% of young adults reported change in sexual attraction over two time points (Dickson, Paul, & Herbison, 2003).…”
