Some people might know about the Gor series. These are a series of...what are meant to be science fiction novels. But they're really more like pornography. Imagine the John Carter of Mars series if Edgar Rice Burroughs wasn't that interested in adventures but was super interested in tying up women.
As far as I'm concerned, whatever lifts your luggage. Having fantasies about tying up women doesn't make you a rapist, or even sexist, any more than playing Halo makes you a serial killer.
However the author, John Norman, seems to think he's some kind of persecuted philosopher. Everyone should read the interview here. It's quite amazing. It's like a twelve year old's idea of what a clever grown-up sounds like. The interviewer completely fawns over him as well.
