The present study investigated the relationships between (exposure to) sexy self-presentations on social network sites (SNSs) and adolescents' sexual self-concept over time. Results from a three-wave panel study among 1,288 Dutch adolescents (aged 13-17 years) showed that more frequent engagement in sexy self-presentation, rather than exposure to sexy self-presentations of others, on SNSs positively predicted the importance of being sexually outgoing (e.g., sexy, seductive, and wild) in adolescents' self-concept 6 months later.
