The present research will assess the prevalence of heterosexual aggression perpetration and victimization in Iranian women and men. Furthermore, the study will examine potential predictors of sexual aggression perpetration and victimization. Prior research suggested the following two predictors of sexual aggression victimization: Child sexual abuse (CSA) and risky sexual behavior (Krahé & Berger, 2017; Moyano et al., 2017; Tomaszewska & Krahé, 2018; Yeater et al., 2019). The potential predictors of sexual aggression perpetration are: CSA, risky sexual behavior, and for male participants also hostile masculinity attitudes (Hannover et al., 2018; Krahé & Berger, 2017; Moyano et al., 2017; Tomaszewska & Krahé, 2018).
