An ex of mine called his “Pedro”. He also referred to mine as “Gertrude” and the “breasteses”
A friend and I have had our breasts referred to as “the qualities”(her) and “The Quantities”(me). We now call them that when we are talking. 
I’m reminded of the Python song: The Penis Song
Isn’t it awfully nice to have a Penis.
Isn’t it frightfully good to have a dong.
It’s swell to own a stiffy. It’s divine to to own a dick.
From the tiniest little tadger to the world’s biggist Prick.
So, three cheers for you Willy or John Thomas.
Hooray for your one-eyed trouser snake.
Your piece of pork, your wife’s best friend, your Percy or your cock,
You can wrap it up in ribbons, you can stick it in your sock,
But don’t take it out in public or they will stick you in the dock,
And you won’t come back.
Oh, thank you very much.
Oh my god! I can’t splort here…my head’s gonna explode!

We prefer the term “wee-wee.” As in “I wee-wee wuv you. I also wuv your wee-wee.”
