Thank you for asking HCM
I have gone through your query.Intially your problem most likely is fungal infection
.Penis and Fore skin part are very sensitive.If you use excess soap or raw dettol it can cause irritation.So the condition you got after that is due to irritation and peeling of skin.In such cases i recommend ointments
which contain antifungal like clotrimazole
antibiotic like neomycin and steroid like betamethasone
.I also advise to use warm water or warm saline water to wash the area and avoid soap and irritating agents.Hope this may help you.
Let me know if you have any further query.
