Hello,
These symptoms can be due to balanitis or yeast infection. Oral course of antibiotics is needed.In addition, ask him not to 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 he should 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.
Also avoid intercourse till he recovers fully. Both of you need to get the yeast infection treated simultaneously.
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.
Hi and welcome. Yes he can contract your yeast infection called thrush. If this is what he has, he can buy some of the OTC creams like monostat.
