I've read many stories about men discovering their wives were less than faithful. After twenty years of marriage they find that wifey has the moral scruples of an alley cat. She invariably claims to love only him. She never deprived him of anything. It was only sex with the other men. I've often wondered: why didn't she tell him in advance? Why didn't he know in advance anyway that his future partner preferred her sex wholesale and he could only offer retail?
