@filmfann I haven’t read 50 Shades of Grey but I have read the Story of O. It really isn’t a love story. I have trouble even calling it erotic in anything more than a technical sense. That book is literally about the dehumanization of a woman. And I don’t mean that in some sort of pearl-clutching outrage. The titualar female is literally kidnapped, trained to be a sex slave, her body subject completely to the whims of her masked keepers and then turned out into the keeping of the man the brought her there. By the end she aspires to be an object to be broken in service of other peoples desires.
It makes for a really good horror, but I think you’d need some pretty out there kinks to find it sexy. It makes American Psycho look like Winnie the Pooh.
