Sex, sex and more sex.
 

I couldn't help but overhear 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: ​“Mate I'm exhausted. My girlfriend and I have sex all the time. She’s after me 3 and 4 times a day.​ She wants sex before breakfast, sex before I go to work, when I come home she’s tearing my shirt off as I come through the door.

She’s got her hands down my pants after dinner. She even joins me in the shower almost every night. I just don't know what to do."
A fellow in his 50’s sitting a couple of stools down, also overheard the conversation.
He looked over at the two young men and with the wisdom of years said,
"Marry her. That'll put a stop to all that".
