This is unrelated to the original topic, but seemed pertinent to the discussion at hand:

I myself am not comfortable with referring to female genitalia as vulva, etc. - it has nothing to do with shame, I just think it sounds harsh and clinical, and I do think that the looks and comments my DD would get in the store, etc. if she yelled out "My vulva itches!" would do more to harm/confuse her than calling it something else. We call it penis for DS, and he has shouted about it in public, but people find it funny...that's societal, I'm sure, and probably where this whole debate stems from... Anyway, DH and I talked a lot about it after reading this thread, and whoever suggested "nethers," thanks! We often call DS's stuff 'junk' as well, as in, "Hey, kid, get your hands off your junk!" if he's playing with the whole area because I think it keeps it lighthearted, which is what we'd like. I feel like nethers is a good female equivalent that doesn't sound so doctor's office...
But that musing aside, the above article makes some really interesting points about why it's a good idea to use the proper terminology from the beginning - as groundwork for later discussions about the bad side of sex. If the first time they learn about sex and sex parts is in the context of "here's bad stuff people might do," it's going to start them with a culture of fear - this is how I was raised, and why I never told anyone about the SA I went through, and why I had/still have a lot of issues. If they know about the neutral/good stuff already, telling them to watch out for the bad stuff is just the other side of it, like strangers or hot stoves or anything else that they have positive or neutral associations with initially that you add nuance to as they mature. I hadn't thought of it like that before, and it's definitely going to influence how we talk about things with both our kids. I thought I'd share for anyone else that found herself eye-rolling through some of the posts -
