In reading the 7 reviews above, I find it amusing that some have trouble separating their fantasy life from their real life. This book is about enhancing one's sexual experiences with a rich imaginative fantasy life. Some, mired in and comfortable with routine and sameness, will find John Norman's mostly male dominated fantasies uncomfortable even offensive. But whether you wish to admit it about yourself or not, all of us, regardless of gender have both dominant and submissive facets of the whole personage that is YOU. John Norman, despite the male dominated Gor series, credibly delves into both of those facets of himself, in that series and in this book.
Enjoyment of this type exploration of one's self requires: the ability of introspection, courage to experiment, inate curousity, and a well developed imagination. I enjoy reading John Norman as an escape from the types of "slavery modern society inflicts" on all of us. (a little of Norman's premise).
If more explanation than that is necessary, you will never understand. Don't buy the book.
If curious, buy it. Enough said.
