I know what you mean. That's a nice thing about the hobby - there's someone out there for everybody.
I've always enjoyed trying all the colors and flavors of the rainbow, so I suppose I've been consistently inconsistent when it comes to a "type". I like a variety pack.
But what has changed for me a lot over time is how I like a lady to present herself. I used to be very into a woman being all decked out in stockings, lingerie, corsets, high heels or boots, makeup - the whole deal. Now I am much more appreciative of the natural, girl next door look (minimal make up, silk robe, or jeans and tank top, and bare feet).
I'm not sure exactly where, why, or how that happened, but it certainly did. I see ads of girls where they only ever show pics of their shoe clad feet - no bare tootsies. At all. And I think "what in the world? ... am I the only one who likes sexy bare feet?". Sigh. Then I realize ladies have a very difficult job - they have to be everything to everybody all the time. That's a pretty tall order.
It's wonderful that ladies are so accommodating to us gents - dressing up (or down) to suit our unique tastes. As we all seem to have different ones. Providers are wonderful things...
