Just because I can't resist this sort of thing (getting grossed out or otherwise exposed to exhibits of weird human behavior), I googled camming and mostly came up with devices used in mountain climbing to secure a perch in rock crevices. There was a mention or 2 of video cybersex, but nothing worth vomiting over in the images search.
That being said, I too am behind the times. A few years back when an employee said that his wife taught 'spinning', I thought "hmmm...now there's a lost art". Glad I kept my mouth shut on that one...
Cheers,
