Sex Cautionary fake documentary movie?


Watched this movie a few years ago, maybe 5-10 years?? Seriously fucked my shit up and was telling a friens about it but can’t remember the name of it. Essentially a fake documentary about Christian teens from the perspective of a new student and how she discovered their secret “anything but genital to genital penetration” parties through her new made friend. It essentially ends terribly with the friend getting raped at a prom after party then she blames her virginity being lost on the new girl not watching her back. I feel like the title had “nation” or “America” in it??
