Swinging Big Business In U.S.

Matt who works as a consultant at a Washington law firm told Reuters that he spends more than $10,000 a year to attend conventions, hotels and clubs where he and his girlfriend can have sex with other partners.

"Any other hobby that I was into at 40 years old is going to cost me $10,000," he told the newspaper. "Dude, I'm addicted to it, there is no doubt about it."

Swinging has turned the lust and passion into a multimillion dollar business. Lifestyles Organization, the nation's largest swinger services company, has annual sales of about $15 million.

 Rick Conner, a swinger and author of an advice book for such couples, puts the number of swingers at 100,000 in the U.S. However, others have suggested the number is in the low millions
