I've noticed, both in myself and others, how specific and detailed we can get when it comes to our fetishes, and find it interesting in that it helps explain why no matter how much we like a certain studio or how attractive we find a certain model, certain tickling position, etc., it may not resonate with others at all. Also for me, some of these things have really evolved over the years into more and more detailed interests. For example, when I was a kid, any site of a pretty girl's/woman's feet excited me, no matter what I view I had of it. Over the years, I've required more and more specific desires, like seeing the tops of an attractive woman's feet doesn't really do much for me, so it became a fixation on the soles of the feet. And while I've always also had a nylon fetish, I realized I only cared to see sheer nylons without reinforced toe. I could go on and on about these little details, but it's insane how these things seem to evolve over time and we constantly need change in what really stimulates/arouses us. I don't know how common this is, but I'm guessing it's fairly common, but probably doesn't apply to everyone. Anyone else experience anything like this?
