I started talking to my kids about sex when they were about 7 and never shut up. Probably over compensating for a lack of similar information in my youth but whatever. It was only an issue once when my daughter told another kid how babies are made who then freaked out and told the yard duty lady in second grade.
Fast forward my kids are now 22 and my son has a new girlfriend. As I said, I’ve never shut up so I told my son I hoped he was confident his girlfriend wouldn’t unexpectedly get pregnant. His response was “don’t worry mom, she has one of those things in her…an IED or whatever”.
I guess kids never stop saying weird shit.
