In my opinio education should teach the biology of sex, and that stds and pregnancy are both out comes if protection is not us. Let the families teach when and with whom sex is ok. But parents should also teach the biology and risks also.
Now did sex kill, or was it the heart attack that happened to end it?
How about we teach the straight, cold hard facts without omitting anything if someone wants to know about it.
Schools aren't going to be advocating that you screw every living being by teaching the facts, they're just going to explain the process, the benefits, the risks, etc.
