I would prefer as much of a fact-based cirriculum on sex and reproduction that we can provide rather than a value-based one.
-The biology of procreation and sexual stimulation.
-As many facts and solid scientific theories about STD contraction, pregnancy, abortion, masturbation, and abstinence (not "it's good to be abstinent," but rather "Here's what you get with being abstinent, here's what you don't get")
Leave the values-based stuff at home.
