cuts in my area

So my boyfriend and I like oral a lot! Which means more hands down there! There is a spot that he seems to catch and the friction causes a bit of a sore! 
I know it isn't an std I have been checked and it's not a flare up, it happens almost every time in the same exact spot. 
Any help on what I can do to help it recover. Lube isn't usually an issue but still the friction happens!
