I wouldn't say I'm an exerpt, but what I've learned is that attention is really the key paying attention to her. If you are doing something and she feels better and better then that's a thing she likes conversely if she feels less turned on, less excited do something else. But just noticing her what did she choose to wear, how does she take it off, what do you like about the shape and contours of her body that will turn her on.
