Risk-taking men are more likely to cheat
Men who take risks and are easily sexually aroused are more likely to cheat on their partners. This is one of the findings from new research published in the Archives of Sexual Behaviour, which also suggested males anxious about their sexual performance may also be prone to promiscuity outside a relationship.
The investigation revealed personality characteristics are more effective predictors for sexual behaviour than factors such as religion and education for both men and women.
Robin Milhausen, a Professor and Sexuality Researcher at the University of Guelph's interdisciplinary academic unit the Department of Family Relations and Applied Nutrition - who conducted the study with Kristen Mark and Erick Janssen of Indiana University - said: "This research shows that demographic variables may not influence decision-making as much as previously thought - that personality matters more, especially for men."
Professor Milhausen added, however, that the study does not simply follow sexual stereotypes, as there are many other variants and factors that might explain why somebody cheats.
Dr Janet Reibstein, from the University of Exeter, commented: "This isn't a surprising finding. Past research on infidelity has shown that background and demographic factors predict very little to it.
"It also accords with research on the differential meanings that sex has for men and women, with sexual performance being more integral to a men's self-esteem than to women's and men in long-term relationships, as opposed to women, feeling more 'unloved' from infrequent sex than women.
"This points to personality-type factors being more likely to be involved in gendered different sexual behaviours than demographics."
