I’m not a teacher but my Uncle made short videos about sexual harassment for his work, being that its about sexual harassment my cousin who was 6 at the time was not allowed to watch, and my Uncle told him that they were movies for grown ups. So when my cousin is in 1st grade his teacher asked him what his father did for a living and he replied “My dad makes Adult Movies”.
I had a kid ask me if it was normal for adults to wrestle every night before going to bed.
I was a teacher’s helper and one day a kid came to class wearing a stretchy cock ring on his wrist. I bet his mom was mortified when he came home.
A friend brought in his Mum’s bright pink dildo. Half the school chased him round the playground trying to get hold of it. Must have been the most bizarre sight when the teacher came out, 150 six and seven year olds chasing a wobbling dildo.
