This won't sound pleasant but bear with me. Her smell could be a yeast infection but most likely it's a mixture of sweat and urine. I mean doesn't your crotch get funky if you don't wash all day? Sweat from being in packed, damp conditions all day.. and then a few drops of urine we didn't manage to shake off after a piss. We all know what our own funk is like so we've got to assume that the girls also get some funk down there. That said it's every provider's responsibility to stay clean so she doesn't turn off customers or get a rep for being unclean. But in the end it's her business, I guess, quite literally.
