Just to start off i'd like to say, what I did was very stupid and I def should have not done it or used a condom, but since I don't own a time mahcine, I can't take what happened back. About almost two weeks ago now my girlfriend and I where fooling around. She was naked and I was also. We wheren't having sex. That night I didn't have an orgasm, but while she was naked she pushed me on her and we started to lighlty grinding(for about 12 seconds). My penis maybe had pre-seminal fluid on it and only touched or went 1/2 an inch into her lips. What are the chances of her being pregnant. I learned my lesson and will always where a condom, but for now I like to know what might happen. Thanks
