I haven't had any experience with, ahem, teenage girls since the 90s but the culture may have shifted since then. In my ancient experience 13 was just too young for anything. Some of them talked the talk but they were just LARPing as sluts for giggles. I think social media just makes it easier for them to get attention without having to do anything besides dress up and take selfies. IRL they won't act this way.
The nose ring has to go too.
