Well, you could leave
Emotional infidelity laying around the house for him to see, maybe he'll read it and learn something, but trying to educate our spouses is a risky endeavor, and more likely to backfire than succeed. However, the fact remains that he has been unfaithful to you, even if not physically unfaithful, whether he admits it or not. I suspect he will not. However, he probably will admit that your marriage is not perfect, and that your sex life is not perfect. I would start from there.
Harley's basic approach to recovery from infidelity is to deal with all the problems in your marriage that contribute to infidelity. So, "Surviving an Affair" is not just a book about recovering from infidelity, it is a book on how to have a great marriage - how to identify the problems between you, and how to eliminate or minimize them. So, my advice to you is to follow the affair recovery path described in SAA, but sell it to your husband as a way to improve your marriage. You can even be honest and say that you feel he has been unfaithful, he feels he has not, and here is an approach to improving your marriage that can accomodate both points of view.
One book he may be interested in reading, if he is a reader and at all religious, is "The Sexual Man", by Hart. It is based on a survey done by a marriage and sex therapist about what kind of men have the most satisfying sex lives. (The short answer is married men who practice monogamy and have empathetic wives, but it is a LOT more complicated than that, and he goes in to some detail about how other sex practices impair one's ability to have a great sex life, which is particularly applicable to your case.)
