Women have no problem finding their private parts - most have to bother with them once a month. But when you need a mirror to find them, most women just don’t bother getting the whole visual picture. Also, unlike men, women are not obsessed with their privates.
Well it would be nice if they could identify them on a diagram even if they cannot see it all without a mirror and speculum. Vulva<>vagina though some seem to think EVERYTHING “down there” is their “vagina” not just the internal canal.
