Thanks. If you like that analogy, there are more. I got the idea from Humiliation, a book of philosophical musings on that subject by Wayne Koestenbaum. Also, Sherlock's assertion that everything in the world is about sex except sex is from Oscar Wilde, and his idea that a fetish is a story masquerading as an object is from the book Female Fetishism. If Sherlock's going to be kinky, he might as well be well read. :P
