I'm sure I'm not the only one on TMB that is having a difficult time really finding any new insights into Christian sexuality. I've picked up several books and sat in the floor reading them at the Christian bookstores and every book feels like I've already read it. Because I have. Most of the things on godly husbandry, godly fatherliness, godly marriage, godly sexuality, gender roles, etc. are almost all the same it seems.
From what little I know, however, I'm not sure how much of this has to do with the publishing houses. When an author submits to a publisher, the publisher doesn't just accept it outright and say, "Yes, we can do this." They talk with the author about editing and promotion and target audiences and handling criticism. And they do this to sell the book. We all know it's easier to tell someone something that they have heard before and possibly forgotten, than it is to come right out and say, "This isn't new, but no one else is saying it, so I will." Especially in the Christian community. In some areas there can be someone who's on the edge a little bit, but still doctrinally sound, and their book may become a success BECAUSE of that. For an issue like sexuality, you're considered brave for even addressing it. Right now I have in my heart a set of companion books for guys and girls, but one specific chapter in each book that I think is very important regarding specifics of body image, are embarrassing enough that it would cause a stink so it would most likely be removed. In the secular publishing market it's not the same. That's why we can find books on bondage, pole dancing, anal sex, etc. and they aren't buried in a paragraph, but are the whole subject of the book.
So the fact that Lehman even addresses some of the things he does, is "edgy" in the Christian community. I was surprised to even see the occasional slang ("hand job") in there.
So, new? No. At least more honest and open than most Christian marriage books? I think so.
