Adult Swingers now, on the other hand, we can make fairly good estimates -- based on information coming from a variety of sources (including the Internet).
Adult Swingers in the past, meeting another couple often took weeks of mailing photos and writing letters before the meeting actually took place.
While most swinging is about two couples sharing fun and swapping partners, many swingers regularly participate in threesomes.
Whether you're looking for something voyeuristic or a full-blown orgy, you can find it online. Whether it's same room sex, a threesome or even an orgy, many sexual activities are included.
At a minimum these studies indicate that a lot of people are receptive to the idea of swinging. As knowledge and freedom expand, so will the numbers that participate.
Only a few years ago, before the Internet era, swingers were essentially a secret society, meeting each other through dating magazines purchased at adult bookstores.
Because of that, it was difficult to even guess at how many swingers there were.
