One of my colleagues has a 14-year old daughter, and she has TikTok. It’s not uncommon for girls of her age to post stuff like “the right place for a hand during kissing”, and it’ll be a (subtle) reference to the throat.

There’s nothing wrong with consuming porn at that age per sè, but without good parental / sex ed guidance it shapes kids their concept of what “normal” sex is before they are given the chance to figure that out on their own.
