How did “Recording Studio” get chosen? And where in the studio? Drum booth, control room, soundlock, vocal booth, or live room?
I’d like to add (without any endorsement or experience on my part) “Pit in back of lane in Bowling Alley”. If it’s a Brunswick machine, the place where the pins fall vibrates, which would make for an, er, interesting time, if you don’t mind the grease.
50 yard line on a football field in a preferably empty stadium. (or in the end zone so you can make endless jokes about “scoring”).
In a tall tree. (just be very careful)
In a library. Books and sex, what more could you want?
I’d have to say in the butt, Bob.
Wherever you happen to be when the mood strikes.
The wife and I are collecting State Capitols. The only rules are it has to be on the grounds somewhere. We have 4 so far. However since Sept 11 we haven’t tried any others as we are concerned about security.
Other faves over the years with various participants:
in a lighthouse
pickup bed at a drive in theatre
in a van full of people coming home from the beach late in the evening who don’t have a clue
in the back of a car with her parents driving, don’t have a clue (oral only, does that count?)
just about anywhere i’ve been out in nature with a girl, woods, water, desert, etc…
in a tent in a crowded campground
in the surf (i told that girl not to let go of her bikini bottoms, we looked pretty dumb when i had to come out of the water, back to our friends, take a towel back out into the water for her…i think the others figured out what was going on).
Rock City
in a cave, while on a tour
public swimming pool, late at night
apt swimming pool
country club swimming pool (these three represent a progession from high school, to college, to suburbanite)
the Fort on St. Kitts
in the backyard
in the frontyard
in the car, parked in the garage (breaking in a new vehicle takes a lot of effort)
in the car, everywhere else
on the highway
in an alley
Fort Nashboro
Battleship Texas
On top of a mountain pass in the Rockies in Colorado, could see for a hundred miles in any direction it seemed
in the bathroom or other room at many different parties, usually with girls i just met
middle of Kyle Field at midnight (didn’t make my million before 30 though)
in the infield at Talledega (never did know her name, come to think of it i don’t even remember how we ended up having sex)
variousl parks, baseball fields, golf courses, etc…
ah, the memories…i’m sure there are more but i haven’t had coffee yet.
During a physics lecture?
Am I the only one that thinks this sounds more than a tad sacreligious? 
“… and that’s why they won’t let your mother and me back into Howard Johnson’s ever again.”
Must these actually be doable?
In the Space Shuttle in orbit.
In a chocolate factory, in a vat of melted chocolate.
In scuba gear in deep water?
Hijack/ how would water pressure 100 ft down affect ejaculation?
Sigh.
But when the nice librarian chases your naked tush out the front door or calls the cops, don’t assume it’s because he/she is a prude. This is pretty common fantasy and suffers from over exposure, in all senses. “Sheesh, again?!”
Veb
Damn you, pravnik, I wanted to be the one to post that. 
In terms of coolness, you can’t beat Antarctica.
The restroom of a major department store.
In a treehouse.
In a rowboat in the middle of a lake.
In a utility room below the grandstands at the fairgrounds during the fair while Bon Jovi was performing on stage.
On a fire escape in the rain
In a B-17 bomber. In flight.
Or any other bomber for that matter. . .

Yeah, I saw 1941 yesterday. . .
We were talking about what sort of subliminal messages we’d want to put on CD’s if we were ever in a band, and that crossed over into the ‘places to have sex’ list. (Mudshark and I are are all about lists, we’ve got the sex list, the bodily fluids continuum, the ‘who would be on our Sargent Pepper cover if we were the Beatles’ list…anyway).
We thought it would be rather fun to go at it one night in the recording studio when the other band members were gone, (in the vocal booth) screw like mad, record it, and somehow dub the session (maybe back wards or at a low volume) into the final release of the album.
It would be the Paul-is-dead equivalent for the new millenuim. “Oh my God, Ray, you can hear their bass player and the lead singer go at it on this one, turn the volume up in that quiet part! Right there!” “They are not, it’s just the bassist screaming ‘cranberry sauce,’ you dumbass.”
Top of the Space Needle.
There’s a unisex restroom in the gift shop and…
On reflection, apologies to all, including the OP, for that post. It might have been on the subject of the question, but not in the spirit.
(I’m a little cranky because we had to chase out the same couple having sex in the library twice last week. The second time they were caught by a kid and her grandmother. NOT a good scene.)
Anyway, I will apologize, stop hijacking this and shut up already.
Sheepishly,
Veb
Aw, don’t worry about it Veb. Completely understandable, after having to deal with that scene.
“Grammy, what are they doing?”
“They’re…they’re reading, Kimmy. We’re going into the children’s section now.”
“No, they’re not reading, grandma, his hand’s on her–”
“Kimmy, I said we’re going to the children’s section now.”
Yeah. Wouldn’t want to have to answer for that one.
