The title suggests a kink approach for wives who just found this out of their husbands. By that virtue, it should not be considered a first-read on the matter for the spouse, who's probably reeling pretty hard...there are better such reads, especially since most discoveries tend to result in bad endings to relationships. If the relationship survives, the book is still subject to a limited audience because most spouses who stick with it would rather look the other way. I just dunno...
