Ok, so I'm 19 and though I'm a virgin I know stuff, I've taken sex ed I'm in college and so on. My boyfriend and I pretty much do everything except sex because I want to wait til marriage, and we are pretty good about keeping it safe. When we do rub up against each other one of us always has underwear on. There have been a couple of instances where I will give him a hand job and he probably gets sperm on his hand from wiping himself off, but then he uses a paper towel to wipe that off. If say, he fingers me maybe 5-10 minutes after doing this, could I possibly get pregnant? I heard that once it is washed or rubbed off or even just dries then there is no possibility. We haven't done anything in about 2 months and I started the pill since then but I have been noticing I've gained a couple pounds and pants fit tighter. Am I jsut gaining weight and paranoid for no reason?
