Abstract
Heterosexual college students completed a questionnaire measuring affective reactions and cognitive attributions pertaining to behavior by a hypothetical relationship partner. Compared to men, women indicated more negative feelings about a partner's solitary sexual behavior. For men and women, a partner's use of sexually explicit material was rated more negatively than a partner's masturbation. Regarding the attributions, there was a difference on concerning the belief about partner satisfaction. Respondents were more likely to see a partner's use of sexually explicit materials rather than masturbation as a sign of dissatisfaction with the original partner or the sexual relationship. Results are discussed with regard to implications for future research.
