lemme try your girl out. She may be the problem....maybe she's too hot. I'll let you know if it's her after a couple of times. It's the only way you're gonna find out .
Are you going into the bedroom with a loaded gun? Dude, spank it earlier in the day, a few times if you must. But when you get the girl in the sack with you it is your duty as a male to please her. Otherwise it reflects poorly on other males.
