Don't ask how I found this, just be glad I did

Some highlights of Sex in Space:

"There will be a few problems with zero-gee lovemaking, but most are comparatively minor and probably may be overcome by superior technique. "

"Another interesting feature of three-dimensional orgies is that the participants, once stabilized, can try their hand(s) at “sexual architecture,” using their bodies to build geometric shapes such as spheres, cubes, pyramids and spirals. Kinetic forms may also be constructed such as “windmills” or “Ferris wheels,” with some bodies serving as foundations and others as rotating members or moving chains. The laws of physics tell us that angular momentum is always conserved, so the rotation of any one part of an architecture can readily be transmitted to any other part."

"This same fluid redistribution causes the legs to become quite thin and the torso and head somewhat larger after a few weeks. Our astronauts aren’t talking, but it’s possible that this effect slightly decreases the size of the erect penis, especially since the heart isn’t working as hard or as fast and blood pressure is down. "

"Pioneers of three-dimensional lovemaking will frequently need to consult their dog-eared copy of the NASA Sutra, as virtually anyone should be able to achieve even the most startling contortions. And the Sex-in-Space Race is already on: who will be first to join the Hundred Mile High Club?"

Onward, upward, in and out young skywalkers.
