Warning, I will be generalizing a bit. After years of marriage, wives tend to stop having sex. Dead bedroom situations where the husband wants sex are common. At the same time, women tend to be disgusted by guys watching porn. A large number of wives see it as cheating and many become emotional about it because they feel they can't "compete" with hotter women.

At that point though, does a wife have a right to be upset? Is it even fair?
