Chances of????

Thats a tricky one to answer. I have been doing that a lot and my girlfriend is not preganant. If anything I would recommend that you get on birth control and then try the pull-out method. When a guy has his pencil in your sharpener, he can still be leaking the infamous pimp juice which can get you pregnant. It is not a good idea to try the pull-uot method without birth control.
