I am just pointing out that the age of onset of sexual activity is a distribution, and that nothing nefarious needs to happen to make it so, even at the tail ends. While I would not want my kids (who are older than 4th grade) to be sexually active at their current age, it is important to note that nothing bad happened in my brother's case.

In a related issue: is banning books going to lead to fewer bad outcomes? Unlikely.

Just out of curiosity, at what age do you think it is appropriate for a human to be sexually active by choice?
