My girlfriend and I believe not to have sex until marriage but the other night we were getting into the moment and she started grinding ontop of me. I was wearing just a pair of pajama bottoms, no boxers under that. She was wearing a thong and a pair of athletic shorts. We started fooling around and I had pre- oozing out a little and I pressed up against her where the tip of my penis was pressing up against her vaginal opening (but with the clothes on) is it possible that a little pre- could ooze through my pajamas, through her shorts and thong and into her vagina? Her period should be within the next 2-4 days. By the way, during it all she said her thong slipped to the side of her vagina so it was just up against her shorts, I don't know if she adjusted them so it was covering her vagina or not. I'm just worried about everything and she said she has 4 days before her period should arrive... and if it doesn't... does it mean she's pregnant? Thank you all ahead of time for answering, I'm just stressing about it all.
