Stronger Sexual Impulses, Not Weaker Self-Control, May Explain Why Men Cheat More Than Women

Posted on September 23, 2013

“Men have plenty of self-control — just as much as women,” says Eastwick. “However, if men fail to use self-control, their sexual impulses can be quite strong. This is often the situation when cheating occurs.”

A recently published study strongly suggests men succumb to sexual temptations more than women — for example, cheating on a partner — because they experience strong sexual impulses, not because they have weak self-control.

Previous research has shown that men are more likely than women to pursue romantic partners that are “off limits.” However, until now, the explanation for this sex difference was largely unexplored.

One possible explanation for this effect is that men experience stronger sexual impulses than women do. A second possibility is that women have better self-control than men. The current study’s results support the former explanation and provide new insight into humans' evolutionary origins.

“Overall, these studies suggest that men are more likely to give in to sexual temptations because they tend to have stronger sexual impulse strength than women do,” says Natasha Tidwell, a doctoral student in the Department of Psychology at Texas A&M University, who authored the study. Paul Eastwick, assistant professor in the Department of Human Development and Family Sciences at The University of Texas at Austin, co-authored the study.

“But when people exercise self-control in a given situation, this sex difference in behavior is greatly reduced. It makes sense that self-control, which has relatively recent evolutionary origins compared to sexual impulses, would work similarly — and as effectively — for both men and women,” Tidwell said.

In order to test their first hypothesis, researchers recruited 218 (70 male, 148 female) study participants from the United States.

Participants were first asked to recall and describe an attraction to an unavailable or incompatible member of the opposite sex. They then answered survey questions designed to measure strength of sexual impulse, attempts to intentionally control the sexual impulse, and resultant behaviors.

“When men reflected on their past sexual behavior, they reported experiencing relatively stronger impulses and acting on those impulses more than women did,” says Tidwell.

However, men and women did not differ in the extent to which they exerted self-control.

“When men and women said they actually did exert self-control in sexual situations, impulse strength didn’t predict how much either sex would actually engage in ‘off-limits’ sex,” added Tidwell.

“Men have plenty of self-control — just as much as women,” says Eastwick. “However, if men fail to use self-control, their sexual impulses can be quite strong. This is often the situation when cheating occurs.”

Men experienced a much stronger impulse to “accept” the desirable rather than the undesirable partners, and this impulse partially explained why men performed worse on the task than women did. However, this same procedure estimates people’s ability to exert control over their responses, and men did not demonstrate a poorer ability to control their responses relative to women.
