It's by Charles Bowden, and it's called The Bone Garden of Desire. As far as I can tell, it's about death, sex, and food. It's several pages long, but I will happily type it out if anybody is interested in reading it (I'll have to do it in installments, though).
EDIT: just because this essay works for me doesn't necessarily mean you'll like it, of course. I'm going out on a limb with this because when I share something I really like with someone and they don't like it, I die a little, but this one I'm going to try and keep no matter what you think. Anyway, just a disclaimer.
