I went to public school so I may be way off base, but I'm pretty sure the sexual organs of chicks are internal.
They talkin bout flappy labia, maybe?
Could just be the way I’m lookin’ at this situation. The female “vag” area is seen, by me anyways, as one (1) sex organ. Individual labeling of the different parts of said “vag” could add up to more than one part - but, hopefully not parts one would see from an automobile on the street. I’ll ask my doctor the next time I’m in his office for his take !
