His Cheating Heart
In light of the revelation about Jesse James allegedly cheating on Sandra Bullock, I have been getting asked a lot of questions about cheating. Why do men cheat? Why would a man cheat on a beautiful movie star like Sandra Bullock? If people like Sandra Bullock, Uma Thurman, and Halle Berry can’t “keep their man” what hope do the rest of us have?
The statistics on men and cheating vary tremendously according to an American Sexual Behavior study, 22 percent of married men cheat. Yet infidelity researcher and author of The Truth about Cheating: Why Men Stray and What You Can Do to Prevent It Gary Neuman found in his research that 1 in 2.7 men cheat.
Historically we have been lead to believe that men cheat primarily because they seek variety in their sexual partners. But Neuman’s work debunks that myth. Ninety-two percent of men in his study said the affair was not primarily about the sex. “The majority said it was an emotional disconnection, specifically a sense of feeling underappreciated. A lack of thoughtful gestures,” says Neuman.
Further supporting the idea that affairs are not really about sex is Neuman’s other finding that 88 percent of the men surveyed said the other women were no better looking or in no better shape than their own wives which supports the idea that you don’t have to be a supermodel to “keep your man.”

Hmmmm, 1 in 2.7 men? I wonder is he speaking generally or within a particular demographic?
His numbers are based on his own study but he believes they apply to all men in the United States.
