For balance, can I say that our ancestors would have had a somewhat different view of "protecting children" from sex than we do. Nearly everyone lived as peasant farmers in rural conditions, often with a basic farm dwelling and often with the farm animals sharing shelter with the humans. It was not like today and privacy was almost non-existent, so children would have been aware of mating going on and accepted it as part of nature. Not recommending we should go back to that sort of lifestyle before anyone starts with the downdoots.
