It seems to me that kink tends to run in clusters. People are into pain, not so much a certain kind of pain; they're usually a bit flexible about how the pain is created. Or people are into dominating, but how they want to dominate, they can be kind of flexible about.
I think that's because the kink is connecting to some sort of emotional need, even though most people don't seem to know what the need it is. Other things connect to the same need. People have favorite methods, but they can be flexible about the method as long as it connects to the right need.
An example of the flexibility I have in mind is that I was never particularly interested in pain. Then I started meeting women who were, who were deeply enthusiastic about the sensation just because it was an extreme sensation, and I am certainly into that. I suppose I'm still not into pain as pain, but I am pretty enthusiastic about making someone shudder ecstatically with a growl and an arm twist or a violet wand. That same thought, though, would be sickening and repellent with a woman who wasn't clear about enjoying it.
Or from the other side, I was never interested in receiving pain. It doesn't do anything for me in itself. But I can easily imagine tying it into my submissive need to show/prove my desire for her, say by a game where I stuck needles through my own skin for touches from my lover.
Then there's other stuff where I'm not flexible. I have very hard limits on verbal humiliation; only very specific kinds are OK. A lot of kinds that I've heard don't connect with my "lift my partner up" emotional need, so it feels to me like the emotional abuse that it is on the surface. Or orgasm denial; that's basically my nightmare made real. Both of those things are liked by many other people when they're playing submissive, but they don't serve my emotional needs.
