a few months back i developed a small lump under the skin on the base of my penis. after a month or so of waiting for it to go away, i squeezed it and it popped like a pimple. now a few months later the bump is still there, just with an indention in the middle (maybe where the puss came out when i popped it). i didnt get the bump until 6-8 months after i last had sex, maybe even longer. sometimes when i squeeze it, a miniscule amount of white puss will come out but its hardly any. it never hurts unless i really mess with it. the closest thing to what it looks like is molluscum but every website says something different about it so i dont know for sure. i dont have any other symptoms of any STD so im really hoping this is nothing, please help me out.
