Hello,
One of the possibilities to be ruled out is STD’s if you are sexually active. If STD is totally ruled out, then the tingling you feel at the tip of penis
, soaps etc) or it can be a skin condition like eczema, dermatitis etc or it can be a fungal infection. Other than that it can be a simple bacterial infection or balanitis.
You can apply some calamine lotion at the rash as it will help in soothing the skin. You can take some OTC oral antihistamine medications like Benadryl or Claritin and see if it helps. If the symptoms persist then steroids may be needed. You have to consult a dermatologist in that case.
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.
