So has rash on his butt

Last night my so was cracking me up because he comes home and was like “I have a rash on my ASS” and I was like “lol what” and he pulls down his pants and shows me 😂 he walks all day and somehow his butt cheek rubbed against his leg and it caused chaffing so now he has this raw spot on his bum and was like “PLEASE HELP ME” meanwhile I’m like dying because it was hilarious that he was like “LOOK AT MY BUTT” * he was laughing too don’t act like I’m a cold bitch

I’m thinking like.. diaper rash cream? What can you put on a chaffing rash that soothes it and prevents more of it?
