Came far too early.
Man goes to the doctors having problems with premature ejaculation.
Doctor tells him when you feel you are going to come give yourself a fright by firing a starter pistol in the air to prolong sex,
Two days later the doctor sees the man again and asks him how he got on.
He said not good. I was having a 69 when I felt myself coming so I fired the starting pistol in the air.
My wife got such a fright that she sh!t on my face, bit my bell end off then the milkman came out of the wardrobe with his hands up.
