When I was an 8 year, I started getting a sharp pain in the tip/inside of my penis. I am currently 17, and I still experience this pain 4 to 5 times a day, on one or two days a month. I have not had sex, or engaged in any sexual activity besides kissing, so an STD is most likely out of the question. I doubt this is a kidney stone, because normally the pain gets worse and worse until you are done passing the stone. There is occasionally some slight red coloring on the tip of my penis, which does not seem to hurt. Standing up and sitting down seems to trigger the pain sometimes, while other times the pain comes and goes for no reason. Anyone experience similar symptoms or have an idea of what's wrong with me?
