A new study from the University of Guelph and researchers from Indiana University looked at how demographics, interpersonal factors and sexual personality affect infidelity. What they found was that men with sexual performance anxiety are more likely to cheat on their partners. Also, men who are risk-takers or easily sexually aroused are also more likely to wander. When it comes to women, relationship issues are stronger predictors of infidelity. Overall, the study found that personality characteristics and interpersonal factors are better predictors of unfaithfulness than religion, marital status, education or gender. For women, if they are dissatisfied with their relationship they are more than twice as likely to cheat and those who feel they are sexually incompatible are nearly three times as likely. Overall, the rate of infidelity between men and women is pretty close, 23 percent for men and 19 percent for women.
The study was conducted with 506 men and 412 women who said they were in monogamous sexual relationships lasting from three months to 43 years. For more on this report, click here.
