Is it scaly ? Any associated redness ?
Any treatment history done so far ?
Is it located in groin fold ?
Can you send a picture ?
The rash you describe can be due to fungal infection and needs to be treated with antifungal ointment or antifungal powder since you describe it as wet . Probably antifungal powder would be more effective .
Also fungus develop more in wet and moist skin .
Hope This helps .
Yes a fungal infection is common if area is constantly moist . Thats why this is a recurrent problem in your case .
You need to wear soft cotton undergarment , and apply antifungal powder liberally .
