Words are important and so are vaginas

So a very controversial topic is the word "vagina" . I said it today in a conversation and apparently it is not "proper" . I understand that it's not the greatest topic or word in the world but it is a part of our bodies and it's better that saying something along the lines of "meat taco" , which I have heard before. So, the classic question-  What do you call your vagina? Do you have any funny names for your special area?
