If you had to teach human sexuality to children or adolescents in homeschool, what are some things thing ok if religious?

Be realIstic: A religious ovum is fertilized just as easily as an atheist ovum. A religious body is just as susceptible to STDs as an atheist body. Ignorance caused tremendous suffering in earlier times. We're blessed with modern knowledge that gives us much more control over them. If your kids don't learn it from you, who will teach it to them properly? Knowledge is power. We owe it to them to give it to them.
