pudendum or vulva
Good thing this thread was revived.
In 2008, the doctors at the world famous Seattle Grace Hospital began a movement to change the official medical term to “vajayjay.” After due consideration, the establisment’s most influential figure adopted the term. And industry observers declared the term official.
Someone I know has a friend that’s taught her daughters to call it their “front butt.”
Don’t call it that.
I dunno, the screenplay writes itself.
I’m just glad nobody calls it a tree chipper. Because that would be wrong.
One of my Sexual Ethics teachers in university said that in some language other than English, a poetic term for vagina is “little hill.” So he said he used the pickup line, “Can I climb your little hill?”
You can always use the movies as your source material:
“Rosebud” - Citizen Kane
“Funny Business” - Ted (Never saw it, just the advertisements)
“Downstairs” - *Without a Paddle *(On Spike last night - whatta stinker!)
Clown hole? 
Mons? As in mons pubis?
I wonder which one the OP settled on.
I must say I find “nether bits” charming, if not particularly romantic.
Mulva?
I love Mariposa, though I suppose there are a lot of Italian words that would sound as sweet.
Big shock: I hadn’t noticed this was an old thread. My heart skipped a beat when I saw Persephone’s name. She is still missed.
Pussy has usually been the word of choice for my GFs, but one called it her pookee. That prompted me to refer to it as her pokie, which she seemed to like better.
That may have been it.
Minge?
Coochie. Or cooch for short.
The rubyfruit jungle.
The Y. As in “dining at.”
Minge sounds like something old ladies would have.
I use Hunnypie - so sweet…
