"Everyone is someone's favourite candy bar." - Ivern, King of the Jungle
I'm of the opinion that in the context of relationships, people are remarkably similar to porn. No matter how nasty, degrading and vile, there's some weirdo somewhere out there who's teetering on the edge of their seat waiting and craving for more.
Just a matter of putting yourself out there and finding your particular kind of weirdo. :)
