Vulva is the correct name for the outer parts of a woman's sexual organs — the parts you could see from outside, rather than anything inside the body. It is the everyday-but-accurate word used by doctors, nurses, biology teachers, health websites and sex-education books. It is not rude and it is not slang; it is simply the right term, in the same way 'nostril' is the right term for part of a nose. Because English has few polite words in this area, 'vulva' does a lot of work: when a health worker or a writer wants to be clear and respectful, this is the word they reach for.
