I have a pimple at the base of my penis. I have tried to pop it and nothing happens. It only gets bigger (size of a quarter) and then when I leave it alone it goes back to normal (smaller than a dime). It hurts slightly when I tough and prod (on a scale of 1-10, a three at worst). There were some hairs on the edges, but I pull them with tweezers. I have put warm compresses on in, kept clean with Alcohol and applied a tropical steroid for the last twelve hours. I don't shave but keep the hair low with a trimmer. Used an edger trimmer this last time. Btw, there is only only bump at the base of the penis. No cluster or other bumps. Any advice?
