I am 15 and i discovered these white spots on my penis when i was around 12 they were located where my pubic hair was. I thorght nothing of them since my pubic hairs where coming out of them. A year past and they started appearing everywhere on my penis expect for the top. Then i discovered one that was much bigger then the rest as it stuck outwards more and it hade a black line over the top.
