Two guys are in a bar discussing their sex lives. One guy says to the other, "How's your sex life buddy?"
The other guy says, "Not too good. Every time me and my wife have sex, she loses interest half-way through. It's very frustrating."
The first guy says, "Yeah, I know what you mean. I used to have the same problem, but I found a cure. I hid a starter pistol under the bed. When she started to run out of steam, I simply fired the starter pistol. It gave her such a fright that she got all excited, and couldn't get enough. I wish I'd done it years ago."
The other guy says, "OK, I think I'll try that."
The next day they are back in the bar again. The first guy says, "How did you get on with the starter pistol?"
The other guy says, "Don't talk to me about starter pistols! Last night we were having a little 69. As usual, she lost interest half way through, so I fired the starter pistol, just like you said."
The first guy says, "So what happened?"
The other guy says, "She bit my cock, shit in my face, and a man came out of the closet with his hands up!"
