The Politically-Correct Term for Beavers

On a canoeing website, a thread about beavers and beaver dams of all things became quite heated and personal. Thinking that it needed an injection of levity, I posted that the word "beaver" was now considered pejorative, and that the politically correct term was "vagina squirrel".

Not only did exactly no one appreciate the joke, but I was soundly excoriated for "foul language", and told never to post anything that shouldn't be said in front of wives and mothers.

Do those people realize that their wives and mothers have those V-word things? What do you suppose they call them? Do their mothers say "Doctor, will my bearded love oyster need an episiotomy?" Do their wives say "Children, it's time we discussed the cave of wonders"?
