Hello. So heres whats going on, yesterday my boyfriend and I were "dry humping" with just our underwear on. After he told me that he had pre cum on his underwear. I got scared so I changed my underwear because I thought if I left it on, his seamen would get through my undies. I'm scared because I don't know if I could possibly be pregnant or not. I'm a junior in high school, help me please. I know Im too young to have sex or anything similar to sex, but I need advice and Im scared.
