One of those responsibilities we parents of teens MUST accept is teaching them about the facts of life–and the morality beyond the facts of life. For some reason, I found this easier to do 20 years ago when I was teaching a Morality class to sophomores at a Catholic high school. But it’s got to be done.
Good resource material is essential when teens want to know the “why” behind the morals. One such resource, which parents can read ahead of time and then share with their teens, is Jason Evert’s Theology of Her Body/Theology of His Body. Yes, both genders in one book–and Evert does expect that teens will “peek” at the other side of the book. It’s a “flipped” book, so in order to read the other side, you have to flip the book over and open from the back. I found that a bit of a nuisance, but I’m not a teen; maybe they wouldn’t care about that so much.
Other than that, this book is full of straight talk and wisdom. I’d recommend it for teens beginning high school.
