In this study, we examined young adults' conversational descriptions of satisfying and unsatisfying sexual conversations with a romantic partner and the relational and sexual outcomes. We coded participants' responses for content, when and where conversations occurred, and the results of conversations. Most often, conversations occurred in residences at the beginning of relationships and addressed sexual pleasure, relationship issues, sexual health, past sexual experience, attitudes/values, and sexual decision making. The results of conversations included relational consequences such as distrust, anger, understanding, and being afraid to talk to a partner, as well as sexual outcomes such as better sex, condom use, and better sex talk. The findings suggest that the costs and rewards of young adults' sexual disclosure have implications for the effectiveness of sexual communication.
