The difference being mainly that these clubs, bars and magazines are all analog and, prior to the wide availability of porn on the internet, were not something the vast majority of people were exposed to. Kinks have existed since sex started. But that doesn’t mean they were (or are) “normal”. “Normal” isn’t meant to be derogatory as I use it: it’s just shorthand for what the 1-sigma group in the distribution considers “typical”

How are you defining kink here? The vast majority of my sexual partners had some kind of kink, even if just in a toned down level. I cannot remember many I had intimacy enough with that weren't into some behaviour or act considered "kinky".

I really don't know how you'd even define the "normal" sex behaviour, there is just so much variation.
