Many years ago, on a business trip to Japan, I was told there were "pussy bars" where the business men would go for a drink after work, and sit in chairs right next to the stage, where the ladies would just sit on the stage across from the men with their legs spread wide open, so the men could stare at and inspect their vaginas. Maybe because in those days Japanese porn required pixelization of all genitals, so that may have been the only way some single men could get an accurate view of a vagina.
No idea if it was just a rumour, or if they still exist...
