I posted a list of potential names for "girl parts" (like, for example, "girl parts" or vagina, etc.) over at Babble and the commenters gave me a lot of ideas I hadn't thought of. I thought the folks here probably would have some things to add too.
It's a question I feel like there isn't a good answer to, but at some point you have to tell them something, cause they're gonna ask.
