We have two girls. Our general term is vulva, but we do get specific and our girls know clitoris, urethra, vagina. They use anus accurately and bottom/butt/booty (learned from a friend) as well as gluteus maximus, minimus, sacro-illiac... (all learned from a song about butt's).
FWIW our girls have blirted it out in public. One of them fell as a toddler backward on a poll after a LLL meeting and screamed "I HURT MY ANUS". Our youngest was prone to running around naked, doing sumo squats, pointing with both hands and exclaiming 'Vulva!'. Our DD's have taught my MIL more about her own body then she knew.
I also bring it up in normal conversation. While I feel we are very conscious of not offending other people this is one are where I will not give. It is more important for me that our DD's have a healthy relationship with their bodies then it is to not offend someone. While doing normal daily activities I will ask them questions. At the grocery store for instance, I will ask them both to get a box of cereal and in the same breath ask them if anyone has ever touched their vulva. It may not be normal for most people, but I want it to be normal conversation in our house. DH talks about it too. And yea, he has a penis and testicles, and an anus
Just tonight we had this conversation after bath with our just 4 y/o:
"Mom, what's this right here that tickles when I touch it?"
"That's your clitoris"
"OHhhhh! I always wondered where that was and now I know!"
I wish more people knew....
