I am 13 I have masteurbated 3 years.I had a pain today after masteurbating,it was to the left of my crotch.the pain is gone but I really have to try to get an erection,and the erection doesn't stay long.did I ruin my penis?did I break it?or will it heal in a few days time?I don't want to see a doctor because my mom doesn't know I used to masteurbate.
I was going to quit before masteurbation hurt me.is it to late?will I ever be the same?

Sounds like you were doing it too often and perhaps too hard, let it rest for now

You didn't break anything, since masturbation is like having sex without a woman. As far as I know penises usually don't break and even if you did wich I highly doubt it will heal.
