Too much sex

I couldn't help but over-hear two guys in their mid-twenties
while sitting at the bar last night. One of the guys says to
his buddy: "Man you look tired."

His buddy says: "Dude I'm exhausted. My girlfriend and I
have sex all the time. I just don't know what to do."

An older fellow, sitting a couple of stools down, also overheard the conversation. He looked over at the two young men and with the wisdom of years says:  "Marry her. That'll put a stop to that shit."
