Everything that everyone just said was in the book I mentioned. As far as learning from a book......everyone is different. I tend to be patient and analytical, so books work for me. I read it, memorize it, and do it. Only you know if books are good for you. I'll also add to compare the information in different books before buying it, or practicing anything in it. Any Tom, Dick, and Harry can write a book, but not all are filled with useful information.
@Indignant: I like to bite too. Not too hard though. Just enough to put a little pressure on and get a reaction. Bite the neck a bit, lightly suck the same spot, and gently lick while sucking. Always gets a reaction -------> Yes that was in the same book the_robot
