The public perception of kink is shifting to match the reality. More and more people are coming to see your typical BDSM practitioner as the man or woman next door who enjoys consensual role-play along with, maybe, a dollop of pain on the side (or elsewhere).
It’s the more accurate view that every group has its outliers, kinky people tend to be well-adjusted and emotionally stable, we’re healthy, high-functioning people. Most of the people who are into kink use it as a way to enhance conventional sexual practices. It’s not all that different from what other people do. There’s a little bit of bondage, a little bit of spanking, and then fucking.
