Hello,
The symptoms can be due to balanoposthitis. Balanoposthitis is the inflammation of the foreskin and glans and can be caused by bacterial or fungal origins or by contact dermatitis. Oral course of antibiotics is needed. In addition, please 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. Retract the foreskin daily and soak in warm water to clean penis and foreskin. In case the symptoms persist then please 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.
Please I really need some advice as I am currently not in a position where I can visit my gp. The thin white layer seems to peel away very easily.
