A while back I used to masturbate and everything was fine. Then about a month ago, I started doing it again but when I went to pee, the tip of my penis hurt and i was only peeing to one side in a small stream so I stopped since it hurt, and started peeing again and everthing from then on was fine until I masturbated again. It's hurt everytime since then so I've stopped doing it. Now I have a huge urge but I know it's going to hurt. What's wrong?
