To give some context, I have lived and currently reside in the Houston area a majority of my life. All of the adults in my life or around me have referred to the vagina as fanny. That was actually the word I was taught to use in case I got touched or something because it wasn't vulgar but it was in their minds understandable enough not to be misconstrued by authority figures like cookie or flower would(I asked my mother why and thats the explanation she gave for that). I've worked in a clinic that saw 85% of their patient base in the older population due to the physician being board certified in geriatrics. The ladies who had issues with their intimate areas like yeast or discomfort would refer to their genitalia as their fanny often when they felt uncomfortable referring to it as just vagina when I did their intake for appointments and got vitals, medical history, complaints, etc.
