Since you said it goes and comes back after stopping the medications, then we have to look into some preventive measures because to me, that's likely where something is going wrong.
First know that fungal infection thrives most in a moist area, so apart from maintaining high level of hygiene, you need to ensure these areas are dry always. You need to get a towel dedicated to wiping this area dry at all time. Unless you achieve dryness, your creams will only do little.
Secondly is reducing the chances of reinfecting the place after you have achieved control. Wash your hands regularly and ensure you change your boxers on time.
Thirdly, Tinea cruris is commoner in obese people due to the nature of their thighs. Try loose some weight if you are obese.
Since your skin is thining already, I will advise you discontinue the use of creams temporarily for now for your skin to recover. Just ensure you do what I advised and see how it goes.
You can recommence the Ketoconazole drug and use for just 5 days. Treating the condition can be very challenging and requires patience. Let's see how you do on these for now. Take care
