I have no idea what to call my daughter's private parts. My son does. When they were taking a bath together he said, "I have a penis and sister has a vaaaaa-giiiin-aaaa." Shudder.
I hate that word. But I'm not a huge fan of cookie, biscuit and muffin unless your smuttytalk'n. And ain't nothing wrong with that. But the idea of her telling her teacher that she has to pee or she'll butter her muffin makes me wince. The thought of shortening it to 'Gyna reminds me of the speed dating scene in 40 Year Old Virgin. "Private parts" works, but it's sort of generic.
And once she's old enough to learn about all the amazing parts that make up her womanhood I'll be at a loss too, because the word Clit just sounds mean to me. And Clit-or-is is odd to say out loud. It reads like an hard to pronounce girl's name; Shaniqua, Laquya, Clitoris. Am I supposed to tell her to call it her hot-box? Love-button? The hidden mystery that your high school boyfriend will neva evah find.
For my son I'm pretty ok with the word penis. Once, I told him to watch out as he zipped up his pants cause he was about to squash his junk. He just looked at me like I was crazy, "That's not junk, that's my peeee-niiis!". So we're clear on that.
I tried to google it to see if I could find something, but that's a topic better left unsearched. I found a few suggestions, but panty hamster just wasn't working for me. Though the search wasn't completely useless as I found the phrase, "Riding the cotton pony" and plan to work that into the conversation with husband.
