This chapter examines the role of three medium types—television and films, music and music videos, and pornography—in the sexual socialization of emerging adults. For television/films and music/music videos, researchers have found that increased exposure to both is associated with more gendered sexual beliefs and more sexually permissive attitudes and expectations. There is also evidence that exposure to mainstream television and movies is related to a variety of sexual behaviors, including age at sexual debut, sexual experience, and risky sexual behaviors. The literatures on music/music videos and pornography share a common interest in sexism, reporting that both types of media exposure are related to sexist beliefs and lax perceptions of sexual aggression. Pornography consumption is also correlated with more negative body image and higher relational dissatisfaction, which have consequences for the quality of emerging adults’ sexual experiences.
