Rash/skin peeling??

I have this rash down between my thigh and vagina, in that like fold area, on both sides, I’ve had it since I gave birth 9 months ago, it kinda comes and goes on it’s own, but now it’s all deep red and the skins all peeling around it, I know I should get it checked out but I don’t have insurance and I kind of feel it might be a problem with me getting overweight after having my baby and suddenly being all sweaty down there, I literally take a bath everyday and make sure I’m as dry as possible after
