Not as advanced as I had hoped, as well as very male thought process in approach…but it was written by a male. Sort of hoping that this is just an intro to scared sexuality and further books will be much more indepth. Lots of anatomy, prerequisite and intro in this book so it would be great as a starter. A fantastic book for beginners. It has just enough exercises and hands on to get you started, keep you interested and wanting to learn more. Have fun…lots of fun.
