If anyone hasn't seen this, it's quite the entertaining exercise...The Human Sex Map
Just click on the link and add the appropriate pins to the map of sexual kinks and fetishes, and see how "well traveled" you are.
No matter how kinky you thought you were, you start to realize, there is much you haven't even thought of. It's also not a bad idea if you need inspiration for adding a little spice to your stories (at least with some regions).
It does make me realize that there is a certain level of "sexual arrogance" related to how kinky we perceive ourselves to be.
