How likely is to get pregnant from doing stuff with a guy & have cum on your hands & then stand up, I had my clothes on & only touched my stomach with my other hand, to pull my shirt down & fix my pants, is there any chance somehow that sperm could've fallen down into my pants and my underwear.? I had lace underwear at the top so scared it coulda gone through. I washed my hands within 2 minutes after I had it on my left one. Just scared somehow that it fell in there. Any risk at all?
