It takes no effort for the woman to fornicate. If a man fornicates a woman is also involved. Guess what? The average woman today has way more partners than the average man. Interesting you say a man can snap out of it, a woman cannot do the same, what I mean is that the damage is done because woman are less rational.
Women will be more selective with who they fornicate with (guy has money, status, or looks) but men could literally do it to anything (I'm not saying they do) because of their high sex drive.
