Of course, it should go without saying that enjoying fantasies about this in no way indicates a desire for it to actually happen in real life. As one insightful counselor put it, it can be compared to how a man's fantasy of rescuing a woman from danger is not an indication that he would enjoy actually, in real life, confronting armed criminals or rushing into a towering inferno.
Like the author and the scientists who's work he describes, I'm not exactly sure where to go with this. When I talked about it with my wife she became defensive and sarcastic. However, she did agree to read the book, and I'm hopeful that something positive may come of it. Anyway, I think it's useful for any heterosexual man to know that the courteous, respectful, solicitous, gentle, egalitarian husband she wants you to be most of the time is rarely if ever the man she wants -- and needs -- you to be in bed.
So imagine this, guys. You're having sex with your wife of several years, with whom you have a great relationship. Though she doesn't feel at liberty to tell you, for her to have an orgasm she's going to need to fantasize that a man quite different from yourself is forcefully having his way with her. Do you think it helps her when you are your usual courteous, respectful, solicitous, gentle, egalitarian self? I'll bet it doesn't. In fact, I'd guess that even hearing your voice breaks the fantasy. Imagine how frustrating it must be for her that the very niceness in you that she loves so much hinders her from reaching orgasm.
I read through all the reviews and I have some comments about the negative ones. First, some say the points made in this book are so obvious that everyone should already know them, while others say those same points are completely wrong. I suspect both factions did not read the book very closely or thoughtfully.
Second, they're right that the book does not answer the fascinating questions it raises, and it is certainly disappointing not have those answers. But a book titled with a question mark, with a subtitle beginning with "Adventures in", surely shouldn't be taken to be claiming to have much in the way of final answers. Anyway, the scientists themselves don't have the answers yet. Why wait until they do have all the answers to have this useful and fascinating information? It could be a long, long wait, and maybe this knowledge can help your marriage in the meantime.
Oh, one last point. I'd have to agree with another reviewer who said that some of the lengthy descriptions of real women's sexual fantasies was in places indulgent and approached softcore porn. The same essential information could have been conveyed in a bit more clinical form. And it does get fairly salacious in places. On the other hand, I did enjoy it!
