U need v.cream.. that will help but soak first to cool it off..hopes this helps
Hi there and welcome. Well, sounds friction related. It should heal on its own. I honestly would put anything on it and try to wear cotton underwear (no thongs) and loose clothing while it heals. You could try soaking in a salt bath as that might relieve it a bit and help it heal.
Good luck! Be careful and remember, we do actually have pubic hair for a reason--- it's suppose to cut down on friction. If you don't have any, just be aware. good luck dear
