annoying body problem #879

so i'll just say it, the skin in my ass crack splits when i work. like right down the middle, my skin breaks open, leaving a shallow cut that takes a couple days to heal. lately it's happened during almost every shift, even when i wore my one outfit that doesn't involve a thong. my skin is just sooo dry, even there i guess. it's annoying and i'm worried it could get infected! if this happens to anyone else, what do you do about it?
