I had sex 3 days ago and very very stupidly did not use protection, 2 days later when I woke up to use the bathroom I noticed several very small bumps that resembled eczema(which I also have periodically) on the right side of my penis and what appeared to be a light rash on my scrotum. I haven't touched the bumps or rash other than when I wash and put cortisone on the area. The condition hasn't worsened and appears to be making very little progress in healing. Sometimes I get eczema on my arms and legs but never on my genitals. If anybody has any idea what this might be please help.
