Rash on inner thigh creases help?

Marli • Lottie Mae norm 3-23-20. Liam Thomas🌈 born 4-7-17. Angel baby 5-4-16. Hubby & I married 11-1-14. Have two Pomeranian `babies`.
I have what I'm going to lovingly refer to as "adult diaper rash" on my inner thigh creases. It hurts like a mofo. I've been putting coconut oil on it. Anyone have better suggestions...?
Also, ignore the stray hairs. I'm 14 days post partum. So I can't exactly shave. -_-
