The frequent occurrence of aggression within committed romantic relationships is well documented. However, little is known about experiences of interpersonal aggression within casual sexual relationships and experiences. This study aimed to describe the occurrence of emotional, physical, and sexual aggression victimization within committed romantic relationships, casual dating relationships, friends-with-benefit relationships, booty-calls, and one-night stands. College students (N = 172) provided data regarding the lifetime occurrence of emotional, physical, and sexual aggression across different forms of casual sexual relationships and experiences (friends-with-benefits, booty-call, casual dating, one-night stands, committed relationships). Emotional, physical, and sexual subtypes of aggression were reported across all casual sexual relationships and experiences. While a higher percentage of individuals who had been involved in committed relationships reported experiencing at least one form of aggression (approximately 69%), prevalence of at least one form of aggression ranged from approximately 31% to 36% for the various casual sexual relationships/experiences. Across relationships/experiences, emotional and sexual aggression were more common than physical aggression. The findings from this study indicate that emotional, physical, and sexual aggression occur across types of relationships and experiences. Thus, the current study underscores the importance of considering casual dating, friends-with-benefits, booty-calls, and one-night stands when assessing interpersonal aggression.
