Hey brother, sorry for telling you here, but I tried to call you and you didn't answer me and you didn't answer my messages either. I found the information you asked for. It's called Naughty Finger Syndrome (when your finger sticks itself in your hole). It is super common in homosexuals at your age and it is not dangerous. It happens when you see another man who turns you on, it can also be a sign of rectal hyperapendicitis. You still have to go to the doctor. Don't watch gay porn and every time you touch yourself wash your hands so you don't get conjunctivitis like last week. If you keep your anus dilated it will hurt less when you put your finger in. ♥♥♥♥, hopefully this helps you
