I have a a bunch of white small tiny little dots on the base of my penis to the "cut off line" where it starts the white color. They do NOT hurt. They do NOT itch. They are pretty much just there. They're just like little, small, tiny, white, little bumps. But not even, you can't even feel the bumps really. I don't know what these are. Please help me out, by the way, I am 16. Never had sex :X So yah, I don't think it's an STD.
I don't think it's an STD either. They're sweat glands, basically. You may find one that is sufficiently well developed that it will excrete a white string, akin to a pimple, but they won't go away, they're just there. Don't play with them, mess with them, or interfere with them, and they won't interfere with you. If one swells up, and irritates, just treat it like a pimple - a gentle squeeze (gross, I know) to expel the string, and it should stay quiet again for a while.
