So me and my bf dry humped. His penis was pressed against me very hard almost as if he was actually penetrating me! However I was wearing thin see through bottoms and lace underwear. He was wearing thin shorts and boxers. I was wondering if it is possible for precm to pass through lace and see through clothes after leaking from his boxers and shorts, making me at risk of pregnancy. He also fingered me deep. He may have touched himself before but when he touched me his hands were dry. Any risks here at all?
