NO, NO, NO, you are completely misrepresenting/misunderstanding what I said. What happened is that the study subjects had around 1/5th the teen pregnancy and abortion rates of the national averages for those two items. The national average for each is 100% which might actually only be 4 or 5 pregnancies or abortions per hundred people. So that 20% would be around 1, but this is just illustrating how the number works, I don’t know what the national averages actually are.
So in the study cohort your daughter has only 1/5th the likelihood of getting pregnant compared to the national average.
I don’t want my daughter practicing behavior that lulls her to sleep with a 20% chance of getting pregnant. That means she’ll practice the behavior much more often and that 20% will eventually bite her.
I’d rather her believe she has 100% chance of getting pregnant. No illusions is best. Therefore, no birth control is best.
