Abstract:
We examined three proximal motives for sexual aggression (sexual persistence after a turn down): sexual arousal, power, and relationship. The MTurk sample consisted of 264 adults: 92 Millennial men (35%), 51 Millennial women (19%), 82 Gen X men (31%) and 39 Gen X women (15%). The motive data, measured by the Sexual Aggression Motive Assessment (SAMA), were unanalyzed data extracted from the authors' previous study of the Millennial shift, a phenomenon in which Millennial women, as compared to older generation women, showed higher levels of sexual aggression, while Millennial men, in comparison to older generation men, demonstrated lower levels of sexual aggression. For all respondents combined, the most chosen motive category was sexual arousal (95%), followed by relationship (49%), and then by power (18%) with 50% choosing two or more motive categories. Providing conceptual support for the Millennial shift, significantly more Millennial women than Gen X women chose motives of sexual arousal and power as reasons for perpetrating sexual aggression. An important finding for the relationship motive is that substantial numbers of both men and women engaged in sexual aggression because they felt that having sex would make the person like them.
