re My comment about letting the parents answer delicate questions, that came from my own childhood.
Picture it: Fifth grade “health class.” (It wasn’t called sex Ed, but concepts were introduced.) TeaCher explained how a woman had the eggs, and the man had the speed, and when the egg and sperm connected, poof! A baby starts to grow.
Now I, as an inquisitive and bright 10-year-old asked a very logical question: if the egg is inside the woman, and the sperm is inside the man, how do the two connect? I remember that the teacher turned bright red and said, “ask your mother when you get home.”
From her answer, I knew there was some secret, and Mom would explain It to me later. She dId. (My reaction was that it was DISGUSTING, lol.)
Let the parents br parents, and let teachers concentrate on arithmetic and reading and writing.
