As a sidereal thought, there are many illustrations of the Kama Sutra positions on the internet. Perhaps you could find one that would suit your inverted 30 degree proposal that would satisfy your inverted desires while at the same time providing salacious entertainment. The only downside that I, as a non medical man could imagine, would be a diminution of the blood supply available for the thought processes involved as a consequence of the necessity of the same source of supply to the piston power required. Still, every little effort in self improvement usually comes with a downside. Alternatively, you could try reading the works of Charles Dickens in a subdued light by a crackling log fire.
