"So, there is my question: how do you think our astronauts did it in the Space Shuttle (and please don't try to convince me it never happened"

 
I defy anyone to tell me this question has been rehashed to death here.

Get your mind out of the gutter. I’m talking about combustion velocity being equal to the product of propellant mass flow rate multiplied by exhaust gas ejection speed.

My recollection is that the Soviet space program was mixed gender at a much earlier point than the US program, and was far more focused on the effects of being in space for the longer term (they had to do something different having lost the Moon race, I guess).

When I used to be even nerdier than I am today, and really paid attention to this kind of stuff, I think it was widely assumed that one of the many subjects of interest for the Russians was "sex in space".

Next time you bang a Russian hottie, ask her what she knows about zero-gee sex

See below.

and discovered I do not have any thoughts on how our astronauts
do it in space.

If you got the wave action right if would reflect back at you for an extra bump...  if wrong it was like having 3 people in the bed...  with the third one interfering!  I wasn't much impressed with scuba sex for the same reason...  unless one has double weights.

Yeah, I spent too many hours of my college years thinking about this too.  

The difficulties seem overstated.  It's pretty easy to generate the necessary friction and motion just by pushing and pulling and pulling your partner, or the woman adducting and abducting her hips. It cuts down on possible sexual positions, but the act itself would be very possible. Other positions should be possible if each partner has some hard surface to push against. You can even imagine a zero g gym with various walls, rings, and bars set up to enable the necessary resistance for certain positions (footrests for him and a hand bar for her, adjusted to the correct angles, and doggie is on the menu).  

I am not sure any NASA astronauts ever did this. The lack of informed rumors indicates the married couple might have been stymied by privacy concerns.  It's probably more likely that any NASA sex was gay. For the Russians, however...

... we decided to do it in a hammock that was high off the ground. Seemed like a good idea until we realized that there was no steady spot for one of us to push against (go ahead & try if you do not believe me). Swinging away, we went at it, laughing ourselves silly...

space cams!

A place in LV has a contraption that simulates weightlessness:

The experience of sex in this environment has been chronicled in a short story entitled "Cliff Gods of Acapulco" by Adam Johnson, last year's Pulitzer Prize winner.  The story is in a collection of his entitled "Emporium."

…another troublesome place to have sex is a Tempur-pedic mattress (or any of the other knock-off "memory-foam" type beds).

They're great for sleeping and all.  However, having sex in one of those things is a little difficult.  After all, the point of the mattress is that it's supposed to "give" as you place weight on it.

So say you're in mish--you "push" down and in--the mattress, rather than offering some resistance so that you can "hit bottom", just sort of gives in to your push--so you gotta keep on pushing.  It's tough to build up the right rhythm.  Any position offers similar "technical challenges"…

…none of which is meant to suggest that the effort isn't worth it.
