Sex in Outer Space

Weddings in outer space are already possible. The Japanese firm First Advantage and the U.S.-based private spaceflight firm Rocketplane Global, Inc., announced last summer they can host weddings in space for about $2.3 million apiece.

So what about sex in outer space? For all we know, sex in space has already taken place. But NASA officials aren't talking about that much.

"To say that astronauts are some superior beings who cannot have interests in any kind of sexual feelings for three years ... I just don't buy it," said Jason Kring of Embry-Riddle Aeronautical University in Florida. Kring also pointed out the possibly negative consequences of pregnancies in a micro-gravity environment.

"Are we going to sterilize our crew members before sending them to Mars?" said Kring, who studies the psychological effects of long-duration space missions.

Has "it" has happened already?

"We don't study sexuality in space, and we don't have any studies ongoing with that," said NASA spokesman Bill Jeffs of the Johnson Space Center in Houston. "If that's your specific topic, there's nothing to discuss," he added, referring to "sex in space."

Science journalist Laura Woodmansee, wrote a book, "Sex in Space," in which she states "honeymoons in space and out-of-this-world sex will be a reality within a decade."

How to do it: The key to successful sex in space is about dealing with micro-gravity as you float around.

In "Sex in Space," Woodmansee describes several positions that might work, ranging from the modified missionary position to seated with "interlocking Y legs."

You would also need props, including a shared elastic waistband or tethers to hold one partner to a stable structure so you don't go flying off from each other.
