text: do most married men have an affair because of trouble at home?   no, you don't need an excuse to cheat. it helps you sometimes mentally but you really don't need one. alot of the times that i have cheated it was because another women did make me feel better about myself. on the other hand it was just exciting to chase another woman. sex was different and exciting for a short time then i moved on to someone else. so to answer you question....no.
