Suggest Treatment For White Bump On The Perineum

Hi, so like a couple years ago I noticed 1 small white bump located on perineum, I thought nothing of it, it s painless, doesn t itch, I ve been tested for many things in the past, have had doctors look down there for different reasons but it s noticeable enough that it s hard not to see. No one has said anything. Over the years it s gotten slightly bigger. But I wouldn t say it s Big. Just compared to when I first noticed it. It s a hard white bump, and it hasn t gone away, I m pretty clean down there. What could this possibly be??
