hi! i’m female (19 y.o). i’m not sexually active other than masturbating. i have an outie, but i don’t think that should be the reason i stink because i clean between the folds and stuff

my downstairs area stinks (front and back). i can’t get rid of the smell, but i don’t know how to describe it either. it kinda smells like old piss, but again, i don’t really know.
i tried everything to get rid of the smell, washing with soap, washing only with water, witch hazel on the booty hole after showering, showering once a day, showering twice a day, bidet, toilet paper, wet wipes,… you name it. my doctor ruled out infections or other illnesses too. i tried shaving, trimming and leaving the hair, nothing helps. i also tried changing diets, again, no help

i don’t know what to do anymore and i’d be super grateful for some tips
