Respectfully, I must call Bravo Sierra on “Sex Ed”.

What’s to teach?

One male & one female, married for life.

Even if you don't teach that it should be "married for life", there isn't that much to the biology unless the kids are planning to go to medical school to be an OB/GYN or urologist. What are the organs, how do they work, what diseases are associated with them and how do you prevent those diseases? Pretty much the same as most of health class. If you spend more than a week or two on it you're just playing with it.
