@vagina_museum I remember a glorious rant by Germaine Greer on a BBC4 program about the origins of words. She asserted that "vagina" wasn't a good word as it comes from the Latin for "sword sheath", and it would be far far better if people just used "cunt" instead.
Somehow, I doubt that the 16-25 year olds in that survey had quite the same problem with the word as Germaine.
