I have one tiny red dot on the head of my penis. It is located about the center of the head. It does not itch or burn and is not raised up, but makes me concerned. I had unprotected sex 3 days ago. I am just curious if this is from friction or an infection or an STD?
Thank you for query.it is not clear about the morphology of rash if only uninfected red dot without symptoms.it may be simple friction. Else needs to be examined to rule out infections. Consult doctor if it does not subside. You can get back to me for any clarifications with the photos. Chat Doctor.
