Prior research suggests that parents, peers, and media are popular sources of sexual information and beliefs among emerging adults. Sex-positivity is an orientation toward sex that emphasizes open-minded beliefs and communication about varying sexual behaviors, preferences, and orientations. The current study investigated whether these sexual information sources were associated with emerging adults’ endorsement of sex-positive and sexual orientation-related sexual scripts, and if these sources and scripts were associated with sexual communication among a sample of college students ages 18–22 (n = 341). Results indicate that learning from television was positively related to sex-positive sexual script endorsement, and that sex-positive scripts were associated with more positive sexual communication. An interaction also emerged between gender and learning from television on sex-positive script endorsement, and between gender and learning from social media on sexual orientation-related script endorsement. The implications of these findings are contextualized within emerging adults’ sexual agency and behavior. Future directions of research are also discussed.
