Okay, i feel weird writing this but i need some help. So one night my boyfriend and i were hanging out and things went a little further then we're used to. He had his underwear on, but was putting his penis "in" (not in cuz he had underwear, but, close) and around my vagina. We both checked for suspicious stains after, but found nothing. A couple days afterwards, i started having brown discharge. I have searched and found several reasons why i could be having this, but none pertaining to the facts that 1) i haven't had sex and 2) i am not on the pill. So if anyone has any idea what could be wrong and could give me advice, that'd be great because i think i may just be overdramatic about this whole thing but i just want to know. Thanks!
