This fetish bollocks was around a long time before porn. It was around when the first humans were around.
History lesson. There was a guy named John Dalton. In 1808 he said to the world, there is a thing called an "atom", and it is the building block of all matter. Wonderful. So before that there was nothing, no earth, no sea, no sky? No; atoms were there at the big bang except we didn't have a word for them. And we weren't there yet.
So today you have words like domination and fetish. But those are just labels for some things which have always been there. Human inclinations, tendencies, things that feel good or natural. Porn didn't invent fetishes.
And what is regular sex? Woman stays quiet, lies down on the bed, man gets on top, three pumps and done, missionary only? Well, you know what, I'm fairly open. If that works for you and your partner, enjoy. But I prefer a menu with a slightly wider selection, thanks.
