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?
