I agree that succumbing to temptation is a moral failure. That being said, I don't think it has much to do with 'trust' and 'morals' as a lot of folks insist.
I think what is more on topic though is that feminism has encouraged more women to cheat, and more women to engage in immoral behavior. The first law of feminism is that men are the ultimate evil, the second law is that women must beat men at everything men do.
