Much of this book is hampered by a fairly narrow definition of a healthy sexual relationship (although not nearly as narrow as many books on the subject) and an annoying habit of cheering on Baby Boomer-style promiscuity while dismissing the sexual liberation of GenXers and Millennials. The solutions are also highly individual and impractical for most couples. The chapter on parenthood has some good insights, so it's not a total throwaway.
