If the woman won't give him enough sex and if he cheats on her, then the Bishop will blame his cheating on her and more or less give him a free pass when it comes to church discipline.
The women always have an advantage in that arena though. If a man randomly asked 100 women for sex, he would probably get slapped in the face (or worse) 99 times, and get laid once. If a woman asked 100 different random men for sex, she would probably get laid 99 times and one man would politely decline, probably because he is gay.
My ex certainly thought (and said) that it was my job to help him overcome masturbation by giving him enough sex.. It was my responsibility to not make him sin...
