HaHa :) Thank you for inviting me to give my perspective.
You know, I was and am confronted with these very questions and statements by children of this age. Anyone who is afraid or immediately feels moral indignation towards the children's statements will probably walk into a trap.
He forgets that he is dealing with children and not with adults. I remember right now the 10-year-old daughter of a friend of mine who copies the language of adults and therefore knows how to irritate the moment. In my eyes, it is nothing more than a test (unconsciously exercised by the child). The child checks, when she says something where she has already felt a certain discomfort before, whether all adults react equally with this discomfort. Of course, she has no idea what she is talking about at all.
I usually react with amusement.
I ask specific questions about the expressed content and want to know, for example, what exactly was meant by "uncontrolled sexual urge", as in this example. The conversations then pass very briefly because the girl lets me see that she has asked out of curiosity or said something shocking, but has no real access to the subject matter. She then loses interest just as quickly because she notices that I do not show a particularly strong emotional reaction. Since she doesn't know what to do with the topic, she then turns to things that have more to do with her world. And that was it. No big deal.
I am the adult, she is the child. I lead through such encounters with humour and ease because I know that children of that age have no experience with sexual encounters. They just parrot what they pick up.
The children learn the moral code of the world around them through parroting. Where they encounter strong reactions, they realise that they have asked or said something that seems to be taboo. I think it is wiser not to get upset by childish statements and to meet them with humour and kindness.
