However, longitudinal studies published during the past decade have raised awareness about the fluidity of orientation among some teens during adolescence and into adulthood.

PMC Canada Author Manuscript PMC Canada Author Manuscript PMC Canada Author Manuscript colleagues (2006a) explored changing orientation labels among older sexual minority teens in New York over 12 months; they found most teens remained consistent, but 30–40% of bisexual teens shifted to a gay or lesbian label during the year, and 7% shifted from gay or lesbian to bisexual; only 2–3% of teens shifted to “straight.” They noted their brief time period and lack of heterosexual teens were distinct limitations to understanding longer-term fluidity or permanence in sexual orientation. Studies by Lisa Diamond (1998, 2000a, 2000b, 2008) documented this fluidity among older adolescent and young adult women over a longer period, charting attractions, labels and behavior. She found relative consistency in their sexual attractions, but up to 67% changed labels and behavior over the course of 10 years, with a small number of young women dropping a lesbian or bisexual label for a heterosexual identity, but far more of them switching between lesbian and bisexual, or shifting to “unlabeled.”["RESEARCH ON ADOLESCENT SEXUAL ORIENTATION:DEVELOPMENT, HEALTH DISPARITIES, STIGMA ANDRESILIENCE," J Res Adolesc. 2011 February 15; 21(1): 256–272]
It makes you wonder how much more frequent this would be in a society that wasn't homonormative.
