NASA International Space Station Alan PoindexterApparently, sex is banned on the International Space Station.

Despite the temptation that gravity-free whoopee must pose, Space Shuttle Discovery commander Alan Poindexter scoffed at the suggestion that astronauts would engage in sexual relations while spending time on the International Space Station.

"We are a group of professionals," Poindexter told a reporter during a visit to Japan. "We treat each other with respect and we have a great working relationship. Personal relationships are not ... an issue."

Poindexter recently returned from a two-week mission on the International Space Station. Among his crew of six were four women, including the first Japanese mother in space.

While this sounds to our porn-perverted minds like the perfect setup for some serious 200-mile-high skin-slapping, it turns out a space station is nothing more than the galaxy's champagne room.
