Specific kinks seem to break down into three categories for me. There's stuff I'm not into, whether because it bothers or scares me or simply because it's not my thing--poop (I feel bad for people who are into poop, because it gets no respect, even kinky people almost take it for granted that poop is icky), most forms of fetish clothing, the whole "littles" thing, forced feminization, etc.
Then there's stuff that I'm into in an "OH FUCK YEAH" way; it hits me right in the vagina just to think about it. Rough mean nasty sex with cruel words whispered in my ear, being dragged around by the hair, being slapped in the face, being threatened and cut with knives, being handcuffed or strapped or tied down helpless, being treated like a slut and a pet and a slave... I'm kind of bad at even writing objectively about this kind of thing.
And then there's a third category. Kinks that don't make me super aroused, but they're just fun. Hypnosis falls into this category; I don't really get gooey at the idea of being hypnotized, but I think it's a really cool and interesting experience. Or elaborate rope bondage, where the focus is on artistry more than restraint. Light fireplay, or anything else with a big "spectacle" element. A lot of forms of roleplay like puppy and pony play. And really any kind of kink can become this depending on the atmosphere and the intentions.
I kind of like having fun with kink. Let's not kid ourselves, I'm in it for the "OH FUCK YEAH" aspects, but fun-only kink makes me happy in a different way. It satisfies some of my weirdo needs without requiring as much risk or seriousness as the heavy stuff. It's also a safer way to experiment, to try things out in a lighter headspace before deciding if I'd like them for "real".
And it just makes me... happy. Inexplicably happy the same way that the heavy stuff makes me inexplicably horny. Getting tied up in a light silly just-friends way still gives me a smile that lasts for a week. I can't entirely deconstruct that but it's true. I guess that's just part of what it means to be kinky.
