> Additionally puberty generally starts in 2nd-3rd grade

No it doesn't. Third graders are 8-9.

The idea of third graders learning about sex and puberty is very strange. We (public school) had health class in 8th and 9th grade where we learned about puberty, sex, and similar topics.

Additionally, it's odd to me that you include mention of "asking teachers questions privately". Why don't 8-9 year olds ask their parents privately? The assumption is that the parents are the enemy. That's exactly what led to this bill.
