Previous research suggests that certain personality traits, such as extraversion and openness, may be associated with sexual risk behaviors (SRB). Exploring psychological and social factors is critical to guide effective sexual health promotion. Background/Objectives: To examine the associations between sociodemographic characteristics, personality traits, sexual attitudes, and risky sexual behaviors among health science students. Methods: A cross-sectional study was conducted with 730 health science students (median age: 21 years, IQR: 20–22 years) using validated questionnaires on personality (BPQ), sexual attitudes (BSAS), and sociodemographic factors. Non-parametric tests and logistic regressions were performed. Results: The results highlight significant differences in sexual attitudes based on sociodemographic characteristics, such as sexual orientation, type of relationship and cohabitation. High levels of pornography consumption are associated with drug use and greater permissiveness. A relationship was established between condom use and openness and intellect. Drug use scored high on extraversion and permissiveness. In relation to the use of dating apps, a positive relationship was found with permissiveness and substance use. Conclusions: The findings reveal a relationship between personality, sociodemographic characteristics, and risky behaviors, underscoring the need for tailored strategies in sexual health education for young adults.
