Recommended with reservations to guys looking to make their ladies scream with pleasure. With this book you get like 2 pieces of philosophy, 5 new techniques, and 3 new (vaginal) spots to play with. Frankly, I think this is more than you get from other sex manuals these days, which are filled with insipid games and awkward techniques. All 10 items are good to very good, but unfortunately they are covered very unevenly over the book's 160 page length. The philosophy is repeated ad nauseum, as a filler, and the techniques are described once and never really expounded upon. This book's content could be easily boiled down into one of those single page laminated guides on Accounting or Bartending you see in the bookstore! (And it would be tempting to bring it into the bedroom, but as Tokunaga accurately states, "The bedroom is no place for theory.")
I also found there to be quite a lot of boasting from Tokunaga: there is a fine line between establishing your credentials and egoistic bragging - and he definitely crosses that line several times.
Tokunaga hates what he calls "junk sex" - which is male orgasm obsessed, brief, and unsatisfying to the woman. Ok, I agree. But he repeats this at least 60 times in the text. It's unnecessary waste.
He describes himself having penetrative sex for, on average, 2 hours. But he doesn't say what he does during that time. He describes a simple breathing and kegel exercise to control the ejaculation, but gives no tips on integrating it into actual sex. And what about the hands, the tongue? At that point is it all just improv? He never says. After all, he recommends at least 30 minutes of loveplay focused solely on the woman, ideally more, so by that time maybe you are already "awash in a sea of pleasure". I don't know, that's just supposition.
To paraphrase his advice: Build your sexual energy with her with your hands, be aware of your love and desire for her as you touch her, forget about your own ejaculation (it will happen anyway), touch her softly and intelligently for a long time all over her body, enter her gently in a sitting sexual position, don't thrust and do breathing kegels to avoid early orgasm. Oh yes, a very good specific tip on foreplay: pull back the clitoral hood before touching the clitoris, and don't vary pressure or pace until she's almost climaxed.
