Is it me or is the swinger movement growing like crazy?

As a high schooler I remember hearing the rumors of school employee's having key parties at the football coaches house, and knew that the football coach left his wife for a woman he was hooking up with at these parties. It's always been a hidden secret of society but it seems here lately its growing like crazy, or at least in my little town.

Married couples with kids in their mid to late 30's, wives all hitting the gym and loosing weight, getting boob jobs and tummy tucks. All of their kids all play on the same travel teams, and its no hidden secret what they do in their free time.

They hire a high school kid to come watch their kids and then they head out to the shop and bang it out for a few hours. One of our friends daughters was hired out to watch the kids one night and a child got hurt, she had no clue what was going on, so she runs into the shop and got a first hand lesson on the in's and outs of swinging.

The funniest, a few weeks ago, a woman was posting pictures on Facebook of her families travel sports nationals trip and accidently posted a picture of their invite to their all girl orgy which include a picture of her getting railed by a guy who wasn't her husband. Before she realized what she had done it was already screenshot and sent all over town. It was quite laughable.

Maybe its just me getting older and getting wiser to the debauchery of adult married people but it seems like its becoming more and more common and out in the open.
