Agreed. Some men, married to cold or rejecting wives, even go to prostitutes to get some warmth and connection.

With men it's not always about sex. That's a silly stereotype.

Sure, most men's main need is having sex. No doubt about that. But it doesn't stop there: most men need also love, affection, appreciation, companionship, connection, warmth, etc.

If their partner isn't giving those things to him, and he finds a woman who does... then he will be tempted to cheat.
