My girlfriend and I were fooling around and we got caught up in the moment, I had a condom on. I was on top of my girlfriend but I didn't penetrate, the shaft was just on her lips, but then couple seconds after the condom slipped off. What are the chances of her getting pregnant if I didn't even penetrate but the shaft touched her lips and the head wasn't near the hole? And this was when the condom slipped off. I felt it was different so it was only for about 5 seconds, with no penetration just her lips rubbing against the shaft. Are the chances of her getting pregnant high?
