It's not you, it's him. No, seriously. Many of the things that prompt men to stray - and about half eventually do - have little to do with you, and everything to do with what's between their ears and legs. Ky Henderson, a male editor at Cosmo, dishes the dirt.
1. He Already Knows You (Obviously)
There's something really nice about getting comfortable around each other - guys think so too. But with that familiarity, he loses some of his intense desire. What is always sexy? Mystery, and nothing is more mysterious than the unknown. And what's unknown? What other women look like naked.
2. His Buddy Kevin Did It
If one of your guy's friends screws around without getting caught, your guy may suddenly look at cheating in a whole new light. After all, men are driven to do incredibly stupid stuff if their friends encourage it or do it first - take, for instance, the Jackass movies, or dudes who wear their hair in that spiky, Growing Up Gotti way. So if his pals tell or show him that there are no consequences, he may forget all of the other reasons there are not to cheat.
3. His Boss Tore Him a New One
When a man's ego is ripped to shreds, the quickest way for him to pick up the pieces is by proving he can still attract, seduce, and have sex with any woman he wants...or, alternatively, with whatever chick is still hanging around the bar at closing time.
