I second Jelktoid and Buster,
DO NOT IRRITATE OR EVEN TOUCH THAT AREA as it can spread.
(This one is for RWG) I got it banging this hot looking 17 year old anally when I was 19. I had the raised kind like Jelktoid. Trying to go to the doctor when you are on your parents insurance is interesting. I also had some interesting experiences at different doctors offices.
#1. Imagine pre-pe and thick body type( wore Husky Tuf-skins as a kid), I had a very small flaccid that was made worse by going to a decent looking young female doc for her to inspect my diseased penis. The worst thing was that she was either a man-hater or trying to make my penis into a liquid hydrogen hammer. It hurt so bad I went into a cold sweat and just laid in my truck with the A/C blowing on me for several minutes.
#2 Went to a male doc next. He used electro-cautery which was painful but very effective. he told me to lay down on the table. I laid supine and he told me to roll over because he thought I had them “peri-rectally”, I then informed him that I was a pitcher only for the visiting team. Also in front of his hot, young assistant with my diseased, turtle-like flaccid.
After that I had no more for 12 years and then got one around the base of my penis when shaving. I went to Radio Shack and got some Component Coolant spray and froze it off myself. But if I was to go to the doctor again I would recommend the electro-cautery, followed up by Podophillin.
