A just-published book by a French science journalist claims NASA astronauts practiced sex in space to determine which lovemaking positions were most feasible when the earth's gravity was out of the question.
Pierre Kohler is a one-time astronaut trainee who says weightless sex was addressed during one of the four NASA space shuttle flights in 1996 which had female astronauts on the crews.
Kohler's book says the lovemaking positions were chosen after computer simulation tests, says the Australian Broadcasting Corp. He says of ten positions tested, six needed the benefit of a belt and an inflatable tunnel to keep the partners together.
And the other four positions? Kohler tells the Australian Broadcasting Corp. it was "just a case of hanging on".
