While it's important to teach your children that same-sex sexuality is wrong, it's no longer enough. The way today's culture thinks and talks about sexuality is incompatible with the belief that same-sex sexuality is wrong. This cannot be ignored. We need to confront it directly.
I wrote this for my preteen daughters (and your preteen and teen children as well). It was written at their level to help them understand that sexual identity is absolutely bogus and same-sex sexuality is always a wrong choice.
