This is the best book I have read on the subject of sex within the Christian marriage. The author is funny, honest, and is mostly balanced. Most of the Christian books related to sex are written by men (some co-written by the wives), and the ones I have read did not do a great job really discussing the woman's side of things. This book is specifically for women, and it is long overdue. I read the book in one sitting and have been reading many of her blog posts since. I also purchased her 31 day challenge on Amazon, and my husband and I like it so far. The great thing about this book is that you can apply her advice straight away. I read the book on a weekend that my husband was away and he noticed a difference the evening he returned. He's even picked up the book and skimmed it a bit because I like it so much. There are three really good things about it, and two minor issues that I disliked.First, she does a brilliant job at explaining the underlying disagreement in many arguments about sex: "Men make love to feel loved, whereas women need to feel loved to make love." I have read many other books that have tried to explain this concept, but she does such a good job of boiling it down to the basics. I think understanding this is great for husbands and wives. Many wives I know think that sex is just physical for their husbands, and it really isn't. Just discussing this with my husband was great because it made us both more aware of each other.Second, she explains the spiritual, emotional, and physical triad that makes up sex. She divides these things into sections but does a great job of tying the three together. By separating them she is able to really focus on the specific component. Some of the other books have a topical approach that integrates all three in every chapter. That can take away from the idea that these are all components which should be addressed and fulfilled in a healthy marriage.Third, she is a great communicator. Her writing is a pleasure to read. It is definitely not literature, but it is full of practical advice. And her writing is not dry at all. You can tell that she has shared a variety of struggles in her married sex life, but truly enjoys sharing and improving her sex life with her husband. She can relate to struggles, but definitely does not let women make a bunch of excuses about their responsibility in their sex life. There is a lot of importance placed on the husband's role, but there is an equal amount placed on wives. I think this is a balanced approach which is applicable for the modern evangelical couple. Husbands and wives both have responsibilities and needs.Now, the two minor issues I somewhat disliked. First, although she is balanced she typically gives women the benefit of the doubt more than men. This is minor and does not detract from the message of the book, but it is something to be aware of when reading. Second, she downplays oral sex (and warns about its potential to lead to selfishness in the bedroom), yet she encourages role playing/fantasies (in the context of one's marriage, and only concerning one's spouse). I think there is more danger in role playing/fantasies than there is in oral sex. She discusses the pitfalls of pornography and erotica (to men and women), and it seems like role playing/fantasies is straddling the line. Another major point she makes to women is the importance of being mentally there when making love, and I think role playing/fantasies could really get in the way of that. On the other hand, oral sex has the possibility of being very selfless, in addition to being a pleasurable way to give and receive expressions of love.With all that said, this is a great book and I would highly recommend it to engaged Christian women and wives.
