Great read, pretty on-target.
What I would add, though, is to stress to all the readers out there to whom this is new information that not every woman is the same and a knowledge of anatomy isn't all you need. Pay attention to her, try different things and make mental notes about the reactions you get...
Let her be on top? Good advice unless she doesn't like that position or is too embarrassed to play with herself with someone else present, and that's fairly common. You'll have to do more work on your own and/or work with her to come out of that shell a bit. I've known more than a couple women who had been convinced by previous partners that it was weird to touch themselves during sex. (WHY are so many guys so insecure in bed? oy...) On the other hand, I remember one partner in particular who told me where to lie, how to lie and ordered me not to move - and proceeded to grind away to climax. MAJOR turn-on.
Just... pay attention to her, you know? Her words, her reactions, random noises - they all point you in the right direction. And it's a goooood road to travel.
