You are suffering from balanopostitis and the cause of infection could be mixed yeast and bacterial infection.
I think your biggest mistake is using of a steroid like hydrocortisone
along with the clotrimazole
Gentle washing of glans with ordinary tap water,proper and gentle drying of glans and totally avoiding soap.
Application of anti fungal and anti biotic cream and totally avoiding local steroids
Meticulous control of blood sugar.
If you get repeated and recurrent attacks of balanopostitis,get the circumcision
done for permanent cure.
