I’ve tried to explore that cave…my wife isn’t a spelunker.
I abwhore spelling miztakes.
coitis looked right at the time
And Euphemism…well, I don’t have an excuse.
I’m going to sit quietly over here in the korner.
A term used for describing a woman who enjoys rather rigorous horizontal activity (or any geometric variation thereof) is to say: “She bangs like a bog door in the wind”
On the general point: “How’s yer father” (As in: Are you game for a little How’s yer father ?)seems to enjoy universal understanding but i know not the origin.
Doing “what newlyweds usually do”
sex, or is that not a eupemisim?
When I first saw this, I thought it was “euphemisms for colitis”. I thought, well, there’s inflammatory bowel disease, Crohn’s disease, ulcerative colitis, Clostridium dificile infection, etc.

Ha…good one
The only euphenism for colitis that I can think of is…I have a load of poo in my drawers.
Gettin’ it on,
Doing the nasty,
Rubbing pee-pees,
The horizontal hula,
Make funny noises together,
urge to merge,
mud for the turtle.
SIGH
Hot Beef Injection
Hide the Salami
Tapping (As in “Who’s tapping her ?”)
parking the limo.
Makin’ bacon 
“the beast with 2 backs and a camcorder”
This is kind of an in-joke…
** Making Cookies **
Someone was talking about “making it” it vague and general terms, and my lil sister happened to overhear, and she piped up and asked what they were making. With a straight face, I said “cookies”
Well, ever since then my and my BF refer to sex as Making Cookies…
Maybe we could combine that with the Fortune Cookie joke; read the fortune then say “…in bed”.
**Making cookies…in bed
the beast with 2 backs and a camcorder…in bed
Makin’ bacon :)…in bed
Hot Beef Injection…in bed
Hide the Salami…in bed
Tapping (As in “Who’s tapping her …in bed?”)
Hmm… not much difference…in bed!
I laughed so hard at this one I had to excuse myself from my desk and go to the ladies’ room - people were staring!
I have one: my friend coined this while listening to her roommate and her boyfriend go at it in the next room: “The Great Thumpity.”
Also, I didn’t hear anyone say “knocking boots.”
For oral sex, my sister and I invented “panning.” And my boyfriend calls it the “wha-wha-wha” which is supposed to mimic the shape of a woman’s mouth while she does it, I suppose.
scrogging
We used to call it “going Dutch on a condom”.
