Must counteract the only other review
This is an earlier work of David Deida, who is a gfted and incredible teacher in the world of masc/femme relationships and the "yoga" of sexuality. This 3 stages is VERY basic DD, but without it you won't understand his regular references to 1st, 2nd, 3rd stage relating. His books are really good, but his audio or video is even better because he has such an amazing presence and presents with depth as well as humor and compassion. DD is the conrnerstone of my personal belief system into the mysteries of men & women. Highly recommend getting started here.
