Flutterby™! : Swinging profile

Very interesting profile of the swinging community, extensively footnoted, at the Society for Human Sexuality.

As far as anyone knows, swinging (as this community exists today, in the United States) had its roots amongst an elite group of U.S. Air Force fighter pilots during World War II. These men were wealthy enough to move their wives close to base, and the fact that their fatality rate was the highest of any branch of service led to an unusual social milieu in which non-monogamy between these pilots' wives and other pilots became acceptable.
