question: I am a 53-year-old and I am circumcised. I have a 4 x 4 mm reddish flat area below the penile head, it does not itch or have pain, sometimes it almost appears normal in color but at other times it becomes more reddish, there is no discharge and does not appear to have any bumps, I have not had a sexual partner in two years and as far as I know I do not have an STD, any thoughts?
