An increasing number of couples expressing their desire to have sex in space have become a cause of concern for scientists, says a report.
The experts do not think that it would be possible to have intercourse in space.
"We've had a variety of people inquire about it," Daily Star quoted Will Whitehorn, president of Virgin Galactic, whose boss Richard Branson hopes to put tourists into space next year, as saying.
"One got in touch about a charter flight so they could be the first to have intercourse in space and get in the Guinness Book of Records. We've also had an approach from people wanting to make a movie," Whitehorn added.
Experts guess that realising sex in space would require spacecraft like the Shuttle to be installed with special "love handles" that would control astronauts floating around.
While two crewmembers on a 1996 Nasa Shuttle are rumoured to have already had an out of this world experience, space medicine expert Dr James Logan insists that lack of gravity would make it difficult for space tourists to have sex.
He believes that the first tourists would instead be more interested in the amazing view.
Dr. Logan, however, added that the first mission to Mars later this century might enable space tourists to enjoy intercourse.
"Sex in zero gravity would more or less be a flailing exercise, quite frankly," he said.
"Sex in Martian gravity might be pretty appealing though," he added.
