Why men cheat? Go here for the details:
To Fulfill His Biology: You know the old anthropological tale. A man's main job, besides killing the saber-tooth, is to spread his seed in order to ensure the survival of his genetic legacy. It's a man's biology to want to wander. Does that mean he should, or that he can't help it? Of course not. But it does mean that a man is going to have strong-extremely strong-biological urges to knock on the doors of neighboring huts. I have had this argument/discussion/conversation with dozens of men and women: Are men predestined to cheat? My answer is no, they're not-despite their biology. But often times, they do have to fight it. Especially after a pitcher and two shots of Jack.
