Also, remember the vulva. People frequently say vagina when they mean vulva. That bugs me. Many people don't even know the word vulva.
Vulva vulva vulva it is such a great word, too.
What's worse is vagina means "sheath" - androcentric, eh.

Yes, 'Vulva' is a good word. I like the term 'pudenda'.
And if you think 'vagina' is androcentric, there's always 'cervix'. I've never worked out why 'cervical cancer' seems to be pronounced 'cervical' ('vic' as in 'victor') when related to the entrance to the womb, but 'cerv-eye-cal' when referring to the vertebrae at the top of the spine.
