I have a small red raised bumb at the tip of the penis head, just at the top of where the opening is. When I spread the skin there seemed to be a small white lump inside. Kind of like a pimple. I squeezed a little bit of the white stuff out and the bump is still there. Just not as bad. It is still a little red Does anyone know what this could be. I know it's not an STD or anything because I was in a relationship for a long time.
