Also don't forget the "sucking" noises

Like unless you work for the circus or something you cannot be sucking yourself down there.

And probably also the poorly handled PTSD that only flairs up when convenient for drama reasons and is entirely forgotten about outside of that

I think it's appropriate for a 14 year old. I mean she's as old as some of the characters in the book going through things.

Like ooo scandalous, kissing... at 14 years old you are entering the 9th grade (aka high school). It's plenty fine. There's a scene in the last book where they get a bit handsy but it's over the bra feeling at absolute most.

HOWEVER, the concern I have with the series is how kinda toxic the romance starts off in the books. Though granted every single YA book from the time had toxic relationships. And I will say that the relationship progresses in a very healthy way.
