What ticks me off is not the book itself but the media's spin on it and the questions it raises and doesn't raise. This spin isn't about sex, it's about power. The bondage narrative moves women back from little power to no power.
A D/s relationship, in its truest form, is all about her wants, her fantasies. Some of her desires may be conscious, but others may be locked in her subconscious. The Dom's job is to build a bond so strong with her that she feels safe enough to unleash her creativity and explore her innermost self.
