Why do women regret casual sex more than men do?

Results suggest that greater feelings of worry, experiencing disgust, and feeling pressured to have sex predicted more regret for casual sex. In contrast, experiencing higher levels of sexual gratification, finding the partner to be sexually competent, and being the one taking the initiative predicted less sexual regret. Predictors of casual sex regret were not moderated by nation. However, relative to men, most of these predictors had a stronger impact on women's likelihood of regretting their most recent casual sex encounter. Discussion focuses on disgust, the key predictor of sexual regret, addresses limitations of the current study, and suggests future lines of research.
