About 5 weeks ago I noticed a pimple looking bump on the head of my penis. At the time I noticed it I also had a pretty bad case of ringworm on my neck. I thought it was possibly that spreading. The ringworm elsewhere is gone but the bump is still there. It doesn't itch, hurt, burn or anything. Nothing comes out if i squeeze it. Its just a pretty small pimple looking bump. There's only one and it hasn't spread or gotten any bigger. I've been faithful to my girlfriend for the past year, and in that time she has been tested and came up negative for any std's. I'm a little concerned though that this may be herpes 2. Can anyone shed some insight?
