Hi, I Have Notice A Change In My Skin Between

Hi, I have notice a change in my skin between my legs and on my private part. I use to use creams for itching after I leave the gym. Now it looks like I have a rash in the pelvic areas. Its kinda difficult for me to wear certain underwear now. Its not bumpy or blisters. it looks like a babies diaper rash. It even looks white. I use to put lotions that smell good down there as well. I want to know what will it take to get my color back and skin. it seems to peel a lot I try not to rub or scratch it but sometimes I cant help it.
