Cheat and get caught and you’ll pay the price, which is often the severing of a longstanding and loving relationship. Here are four reasons a man might give to justify cheating on his wife, according to Men’s Health editor David Zinczenko, author of “Men, Love & Sex: The Complete User’s Guide for Women.”

To fulfill his biology
“A man’s main job is to spread his seed in order to ensure the survival of his genetic legacy,” says Zinczenko. “It’s a man’s biology to want to wander.” Of course, he’s quick to point out that doesn’t mean men should wander.

To get attention
Some men cheat because they aren’t having frequent sex at home, but others who do have frequent sex at home still cheat. Why? “Because cheating isn’t just about the sex,” asserts Zinczenko. “Just as a woman who cheats may be seeking more affection than what she’s getting at home, a man often cheats because he’s seeking the attention that he no longer gets at home.”

To get out
Some men want to get out of their marriage, but they don’t have the guts to properly end it. So they cheat in an attempt to drive their wife away. For some men, “the only way out is to commit the relationship sin that drives a woman away for good. It’s not right, but it’s what happens,” admits Zinczenko.

To change up his playlist
A long and loving marriage is often about comfortable routine. For some men, that routine may be boring. A new relationship adds zing and spice to life.
