Perhaps the most embarassing book I've ever pulled out on the subway or in an audition line...the cover not only has a large white flower but the blaring "real sex" title with only the tiny subtitle that makes it all okay. That being said, it's a great read and one I would recommend for anyone in the church. I had the delight of meeting Lauren Winner and attending a women's retreat where she spoke on this topic among others. She is a smart, smart woman and I especially love reading her books now that I can hear the funny way she says "rather" and picture her vintage wing-tip glasses. The whole premise of the book is that sex is an issue that is central to the life of the church and that it should be done (or not done) in the context of community. One point that really had me thinking was the church's present idolatry of marriage and how we are divided into "singles" and marrieds" when our real identity should just be as Christian brothers and sisters.
Read the book but maybe spend 5 minutes to put a cover on it if you don't want disapproving stares on the subway.
