Threesomes seem like the group-sex du jour, but swinging parties still rage in China, where at least a dozen people face jail time for attending spouse-swapping events. The defendants all found each other through a website initially intended for people to complain about their marriages. In America, you can also (legally) use the Internet to discover whether you'll find partner-swapping delicious. A quick search of Meetup.com came up with plenty of groups for those looking to swing.
Would you give swinging a try?
