OK, here's the thing.. I suspect I had lichen ntidus on my penis before cause I have lots of tiny little flesh coloured lumps. I didn't think anything of it. So about 6months later I have now developed a red spot on my penis (On top of one of the other lumps) it is no bigger than 1cm and has a white head. Ive never had sex before so I'm guessing its not an STI. Could it be masterbating too much? Any help is well apricated, thanks.
