I'm a woman, and I read "For Women Only" first.  In fact, I read that book several times, started to apply it, told my boyfriend about it, and then asked him if he'd like to read "For Men Only."  He happily agreed.  I first read the book (constantly thinking, "You mean, men don't know that!?!") while I also marked how I would have answered the survey questions.  My boyfriend has now read this book several times and has started to apply it.  He says he loves how I treat him (using information from "For Women Only") and I'm in bliss right now from his efforts to apply what he learned in "For Men Only."  I've read other books on similar subjects, but none really get to the heart of the issues like these two little books.  Thanks so much for writing them!
