Vore. I'm not into that crazy hardcore guro stuff, but I like seeing someone get swallowed up by some slimy creature.
I also like furry porn to an extent. If they have more human features than animal features. I'll like something like this, (Where I can easily identify what the animal is) but not this, (Where they look like some type of dog-weasel creature).
I also like feet, but who doesn't?
