Hi all, I've been a long time reader here. I just wanted some advice, and you folks seem pretty well informed. Anyway, I was fooling around with my girlfriend on Friday night, and I was rubbing my penis on her vulva after things got heated. Afterward, my girlfriend expressed concern over getting pregnant, and I've also been worried ever since. I've tried Googling on the topic, but all resources seem to suggest that there is a chance, but I find it hard to believe that pre-cum can travel from the entrance of her vagina to her cervix. What do you guys think? What should I do?
