“A woman riding a horse surges with its impulses, while the horse’s pace incorporates her shifts and pulls. The movement of her body extend speed and retardation and the feel the thrill of speed and the soothing decompression of slowing down. These movements extend neither toward a result nor a development. They are figures of the repetition of compulsion; we stroke a calf each night on the farm, we ride a horse though the woods with the utterly noncumulative of orgasm.”
