Hi! Im 17 and The last night I was out with my boyfriend and I just touched his penis that had pre sperm all over it and I wiped it off a little. When I came home like 15-20 mins later, I touched my underwear on the inner side ( the place where vagina exactly is ) but the problem is that I forgot to wash my hands before doing that and I didn't change my underwear when I went to sleep. Even though I'm convinced that there are a really low chances to get pregnant this way I'm not really sure! Need some answers. Thank you!
