i have a red area on the rim of my penis head, in some light I cant see anything but in others I can see two lines that run parallel to each other up and down, I was tested for gonorrhea, syphilis and chlamydia and all came back negative, no real bump just that spot which has been driving me nuts for 2 months now. No pain no itching no burning, was never filled with any fluid. Gets very red and kind of shiny when aroused.
