I’ve talked before about kink and non-monogamy and the overlap between the two in the public kink-o-sphere. Non-monogamy and kink certainly don’t NEED to go together, but they often do for people who enjoy kink outside of the bedroom.
When I got into the kink Scene, I was surprised by just how many kinksters were some form of non-monogamous. It was a lot. Not everyone. But ALMOST all of the kinksters I know, and by that I mean people who go to kink events, are at least a little bit non-monogamous.
