Theorists suggest that adolescent girls’ sexual socialization can influence sexual risk reduction and positive sexuality development, although adolescent girls’ positive sexuality development is understudied. In this study, we applied a sex-positive framework to explore sexual socialization experiences among a sample of adolescent girls of color recruited from community-based organizations that serve youth with heightened needs ( n = 50; Mage = 15.62, range = 12–19; 58% Black/African American; 76% heterosexual; 58% sexually active). Specifically, we examined girls’ reports of messages about sexuality they have received from their teachers, parents, health care providers, and society at large. Participants completed brief, semi-structured qualitative interviews. Inductive thematic analysis was used to analyze the data. Overall, the adolescent girls described how they navigate primarily sex-negative sexual socialization messages from adults to develop positive sexual selves. Within this narrative, we found five themes: (a) Adults deliver one-sided communication that adolescent sex is inappropriate and risky; (b) Gendered messages restrict adolescent girls’ sexuality; (c) Naive adults can’t be trusted; (d) Exclusion of same-gender sexual experiences endangers adolescents who are lesbian, gay, bisexual, queer, and with other nonheterosexual orientations (LGBQ+); and (e) Messages about sexual protection can help but may still restrict adolescent girls’ sexual choices. Implications for adolescent girls’ positive sexuality development are discussed.
