I dated a woman once who, between you, me, and Frink's mom, was into BSDM stuff. So I'm no prude on this issue.
But DAMN 50 Shades of Gray is boring, unsexy, and really creepy. Even the movie previews aren't sexy in the least (well, maybe that song).
What boggles my mind is how something so dull and awful become so popular. Is our bar for 'lurid titillation' so low?
