I have this exactly, mine itch or feel irritated occassionaly. Please someone respond to this! lol I took Accutane and they appeared shortly after that.
One more thing, they really show up when I'm erect. Which makes doing something with a partner very nerve racking, and I have been avoiding anything since this first happened! I have never had unprotected sex, but experience a burning sensation on the part of my genitals that are touching. Possibly from sweat as I do sweat alot from that area :(
