question: Ok a younger friend of mine. (Swear it really isnt me. Hes like my little brother) hes 16. He asked me about a bump on his penis. He says its on the top side, on the ring at the base of his penis head. I thought it couldve been papsules but he said it was just one and that he cant really see it and theres no color change but he can feel it and can slightly see a rise in the skin. Looked around the web and the most similar thing i foind was that it could be a pimple. Told him and he said he doesnt think its a pimple because its hard and "feels like BONE." I told him it should go away on its own and told him to "leave it alone for a while" and see if it gets better. Just wondering if you know what it could possibly be?
