I believe its a normal nature oof men to always want more than a woman. But religion has helped men to some extent in sticking to only one wife. But most men still secretly have affairs outside. I think only God can help a man not to cheat
From what I have seen, the ultra-religious men are the ones who are crazy after sex. In my hometown, I have seen ultra-religious Muslims frequenting red-light districts. As a matter of fact, these people represent the majority of the clients in brothels.
