Hello,
These symptoms can be due to eczema, yeast infection or balanitis penis. For this you should consult a dermatologist and get a KOH examination of the skin scrapings done to confirm the diagnosis. If the white spots are not easily scraped off then vitiligo should also be ruled out.
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.
