Probably a ton. :P
A few years ago I saw a post saying that kinks/fetishes can usually be sorted into some combination of feeling loved/wanted, gaining or forfeiting control in a safe way, and just tickling your senses in a way that feels good.
So, nowadays, anytime I see one I don't understand, I just pretend like it's a metaphor for a want or need in my life, and even if that doesn't make me totally understand it, it at least puts me a little bit closer. :D
