If you are engaged to be married, read this book. While there are a few areas that we disagreed with the authors, for the most part it was an excellent tool to starting our sex life. This is a must for couples to dispel common misconceptions and expand what knowledge one already possesses. God made sex and in marriage it is to be enjoyed and not a great mystery. Both of you must read this to get the full benefit and openly talk about this one aspect of your pending marriage. To get a good balance try reading this one with "Intended for Pleasure" by Ed Wheat to take you beyond the honeymoon and give a better grounding of the theology of sex and marriage.
An excellent instruction manual on how we can give our bodies to each other in marriage as commanded in I Cor. 7:3. "Unto the wife, let the husband render what is her due, and, in like manner, the wife also, unto the husband." The epilogue is wonderful. "Two become one: A symbol of Christ and the Church." A required book for all engaged or married couples.
