Differences in sexual infidelity as a function of gender have been commonly reported.
It is more common for men compared to women to engage in extradyadic relationships.
In that study which involved 19,065 people during a 15-year period, rates of infidelity among men were found to have risen from 20 to 28%, and rates for women, 5% to 15%.
A survey conducted in 1990 found 2.2% of married participants reported having more than one partner during the past year.
Many studies using forced choice questionnaires have found statistically significant results supporting an innate sex difference between men and women.
The National Health and Social Life Survey found that 40% of married men, 16% of cohabiting men, and 37% of dating men engaged in acts of sexual infidelity compared to 1% of married women, 8% of cohabiting women, and 17% of women in dating relationships.
These differences have been generally thought due to evolutionary pressures that motivate men towards sexual opportunity and women towards commitment to one partner.
In general, national surveys conducted in the early 1990s reported that between 15–25% of married Americans reported having extramarital affairs.
People who had stronger sexual interests, more permissive sexual values, lower subjective satisfaction with their partner, weaker network ties to their partner, and greater sexual opportunities were more likely to be unfaithful.
