Ok so i am 20 years old and i am going thru a curious phase and i have been having unprotected sex with a guy. We had sex a few days ago and now i have a bump on my butthole. It looks like a zit from what i can see cant really look at it. I shaved my but so i am thinking maybe just an ingrown hair. But i dont know if it could be a disease or just a hemoriod i have never had any before any help?
