Etymologically and linguistically, Ozme52 is spot-on. I'm the first in line to say that, yes, language is critical, it is important. We need to understand and be understood. But it's also possible to become overwrought on the whole business of definition.

I guess it's my preference to lump fetish, turn-ons, and what have you under the less-specific rubric of "kink." If "it," be it an object, action, thought, situation, visual or auditory stimulus, what have you, gets you going, gets you hot, wet, and nearer to your happy place, let it be your kink. Or kinks. Spending less time parsing, and more time doing, well, that's just plain good for us.

This maybe isn't what you were after, but I hope it is nevertheless helpful.
