This one has been around for a while but I heard it again last week.

So a married couple are having problems in their relationship and decide to see a marriage counselor. The counselor turns to the wife and asks what the problem is.
The wife says “My husband suffers from premature ejaculation.”
The counselor looks at the husband and inquires “Is that true?”
The husband replies “Well, not exactly, it’s her that suffers not me.”
