Hello,
This redness of meatus can be due to dermatitis skin or balanitis skin. First of all, don’t use any cosmetics on the penis, instead use some topical antimicrobials like Bacitracin or Lotrimin. Also corticosteroids and topical immunosuppressants can be used but they are available under prescription. Also retract the foreskin daily and soak in warm water to clean penis and foreskin. In case the symptoms persist then consult a urologist/dermatologist for evaluation and antimicrobials and steroids prescription.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
I would really appreciate your response.
And one more thing. Just this morning I discovered a tiny reddish white lump on the skin of my penis. It doesn't itch or hurt. It looks like a very tiny mosquito bite. What can it be? Will it go away after a few days?
