John Norman, who wrote the Gor books, also wrote a non-fiction book called "Imaginative Sex." It is an interesting read if you can find a copy! The man definitely had some ideas on sex and the role of men and women in society. But, did you know that the first Gor novels were based in part on a series of novels written by Edgar Rice Burroughs of Tarzan Fame? And that they were originally intended to be an allegorical commentary on society and culture of his time. And all you were thinking about was big hairy men and soft curvy slaves. . . .
