Fungal infection for 6years at Groin are

I have been suffering with fungal infection at Groin area and on buttocks even on penis also(just saw few days ago)  for 6years , I have used lot of medicines and ointments but after complete cure also it's again starts at one point and again spreads. I have used lot of tablets like Trbinaforce , itriconzole etc and lot of different ointments (some had steroids but I didn't know at that time ) so now skin has become thin and if once I start rubbing to satisfy the itching ,then immediately skin cuts and blood comes , if once I start rubbing ( with finger nails or without nails) because of very intensive itching I can't stop rubbing until blood comes by cutting of skin. Some times I think if I can able to ignore that intensive itching for 1month I hope cure will take place , but cannot stop rubbing with nails at itching areas ,if sweat comes means it signs me be ready to face intensive itching at groin and Iam From AP State , becaues of my work nature  can only  consult by online only.
