Why do guys cheat?

Sometimes it's becase they think that they can get away with it. Other times it's because they did something stupid like get drunk at a party and they only find out what they did the next morning. Some people have said that it's because they get some sick confidence boost from it. I agree, sad though that be. Often, when a person (girls and guys) comes from a background where cheating has happened, it is more likely to happen again. It's the same with divorce and multiple girlfriends/boyfriends, and they have no stable relationships.

Sometimes It's a confidence builder. Guys want what they can't have. It could be they're tired of the relationship or are done with the relationship. Sometimes a feeling of power...like the 'ol another notch in the belt kind of thing.

For so many reasons. It is crazy reasons that usually have nothing to do with us at all. Because they want to get away with it and feel the rush. Because they think they can have who ever when ever, they feel they need to explore their options, they are unhappy with themselves, they are addicted to sex, they are just jerks, they are scared of the relationship and feel they need to get away, they want more attention, they want to know if they still have game, there really are so many reasons all ridiculous and not very helpful but hey I tried.

Same reason girls cheat. Confidence boost, the fact that it's taboo, or maybe they're bored with their current relationship. It can be a lot of different things.

There's no real answer to that question they cheat for all types of reasons they become bored with the relationship or they might just be horny.
