Me and my girlfriend were fooling around and I started to hump her, and I was on the out side of her vagina, im not really sure were I was because I didn't know her pants were down but I was in that area, but I wasn't inside of her. And im pretty sure that some precum came out but I didn't ejaculate on her. What are the chances of her getting pregnant. Because she is stressing herself out and starting to stress me out too.
