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.

she means you do not try to fart when you cum..or..the gravitational pull is equal to the deep thrusts..

I can get my mind out of the gutter, but never erase my junior-high level of humor.  Thanks Daddy, for stating the obvious, before I had time to put my drink down!

You mean Neal Armstrong and Buzz Aldrin...?

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 your response was directed at my reply to the OP, I probably goofed by not making it clear that I was quoting and replying to the OP's question.  

So...whaddya do about an Irish nitwit, who has a fondness for "Russian"? Why do they call it "Russian" anyway?
Have to ask. What is zero-gee sex? I suppose I could google it, but doesn't sound as fun.

The 2 suit !!!!! I love it, sure beats handcuffs....oh and keeping it fitting with a response below....

it wasn't called "Russian."  It was called "Swedish."  Not sure why, or why it changed.  But if you go to The Urban Dictionary, it's still the 9th definition for "Swedish."  Either way, nicky likes it.

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.

Not sure MacD - perhaps she is referring to the ejaculate counter-thrust that must be overcome to avoid one or another of the participants being "ejected" from Vmax... as in Ejaculate Mass Flow Rate x Ejaculate Velocity. A well-timed fart could assist with this problem. Perhaps it would be much simpler in zero gee to simply counter the ejaculate thrust with an equal or superior suction?  

perhaps we can get Miss Rasha to demonstrate the counter thrust theory..her ejaculation rate is 100%..her "V' is always at max..

The lava lamp and black light posters all died years ago, but I'm clinging to the bed still.

mrfisher:  the last living hippy.

space cams!

I would love to delve into those mechanics "in depth" with Rrasha... she seems on top of her physics game. Wonder how she is with Physical Chemistry? Gotta love hot, nerdy women!

Ve²=KRgasTc[1-(pe/pc)(k-1)/k]/(k-1)

A place in LV has a contraption that simulates weightlessness:

…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.
