So this is TMI

My boyfriend and I haven’t messed around since the morning of January 2nd, until January 20 again and now I have stinging whenever I pee or touch it on the outside under my vagina hole. I know it’s not a UTI because it’s not like burning inside and I don’t have any symptoms. Maybe he’s torn something? He tried to go at it when my “juices” weren’t fully there and I think that’s what made this happen. Are my insides falling out? I want to know if anyone else has had this “problem” because it hurts for a day, comes back the next and it’s not so bad so, we do it again then it’s fine. Just gets a little sore.

Btw he’s packing like 7 inches I’d say about 1.5 inches thick and my doctor said my vagina is small length wise. Thoughts?
