I hope someone can shed some light on this problem. I was having sex with my girlfriend and hurt my penis when I tried to force it in. It hurt a little bit, but not that much. I ended up with this bump on the left side of my penis. It is near the top of the shaft right below the head. It almost looks like a half ring and just kinda sticks out more. It doesn't really hurt but it is uncomfortable. Does anyone know what I'm talking about?
