Documentary: The Man Who Ate His Lover (Vorarephilia).

Another documentary on the subject of paraphilias.

This one addresses vorarephilia (and masochism). Vorarephilia is a sexual preference for eating another person. It's likely very rare, although we don't know for sure - there isn't any research available. It's presumably even more rarely acted upon. However, there are a few recorded cases. The one described in this documentary is the most well-known.

From the description:

Consider the following story line for the ultimate video nasty. Single man meets radical male masochist on the Internet. On their first date, the masochist offers up his penis as main course in a romantic dinner for two. After some teething problems over the best way to prepare the food, the two men enjoy a meal of garnished genitals. Satiated, and feeling woozy, the masochist is led upstairs to the bathroom, where he is left to bleed to death. Hours later, our host pops in to see how his date is doing, and finishes him off with a knife to the throat. He then butchers the body and barbecues the meat.

Even as fiction, this extreme tale of human weirdness would be difficult to stomach. So how do we respond when two middle-aged computer engineers turn this incredulous plot into jaw-dropping fact? Two words: shock and awe. Just when you thought you'd heard it all, along comes a German cannibal, Armin Meiwes, and his willing victim, Bernd-Juergen Brandes, to rewrite the book of bizarre human behaviour. Rarely has a criminal investigation aroused such ghoulish curiosity or raised such difficult questions about the dark places that the human mind can go.
