It's really difficult to rate this film as it is a curiousity piece rather than a pud pounder. Auto-fellatio can be titilating and drive me mad with jealousy. But auto-fucking? If it were incoroprated into a traditional fuck scene it might be very exciting, but as an end (pardon the pun) in itself (pardon this pun, too) it doesn't engender much heat. It's not even exciting for the participants. It's just "look what I can do". I didn't find any of the performers a turn-on either. (Maybe they learned to do this out of desperation.) I kept recalling a scene from the novel Goldfinger where Goldfinger is about to castrate Bond with a laser beam. "Go fuck yourself, Goldfinger," our hero shouts to the villain. Goldfinger turns back, smiles coyly and says, "Alas, Mr. Bond, not even I am capable of that." These guys are.
