PolyOz

Another variant or modification to monogamy, involving sexual exploration in an environment structured to contain it without damage to an otherwise monogamous relationship. Like polyamory, it involves honesty and consent. Unlike polyamory it typically tries to stringently avoid love, romance or relationships outside the existing pair (though friendships are OK), and is engaged in mainly by couples (though some groups allow single women as well; rarely are single men allowed). Lifestyles is another term used for this option.

The swinging subculture is generally very different from poly subculture, and almost nobody could fail to notice the difference in conferences, gatherings, parties, magazines, email groups or other manifestations of the two movements. Nevertheless, a few people are involved in both movements, or tend to operate in a grey area "in the middle". Human lives and hearts don't always fit neatly into a set of mutually exclusive boxes.
