Well, in that case it isn't porn. I didn't buy it, much less jerk off to it. Besides, I'm taking a sabbatical from milking the mongoose.
I didn't get it, so I only got to thumb through it. But given what I saw, and your and 3some's proclivities, I would doubt it prove use full. That's not to say you won't though.
As for myself, I didn't get it because...Well WTF good is a book on sex to someone who a) has said No to bad sex, b) generally doesn't get sex any way, c) is prone to anxiety attacks while reading dating/relationship/sex books.
