"I'm not seriously tempted by S/M because I do my own self-flagellating — I write. Who needs anybody to discipline and punish me when I've internalized it so well, forcing myself to that desk every day, berating myself for any extended time away from it? I've got my own torture rack going. And it doesn't even bruise the skin."
— Martin Duberman, Cures: A Gay Man's Odyssey
