Somehow I've got the impression that there are more coming-of-age stories about boys than girls... and that's why the effort here is to pay attention to the ones telling the stories of girls, and preferably not only those made in USA. As a result of that, here you have Turn Left at the End of the World (2004, Avi Nesher).
The plot is that of an encounter of two girls - both immigrants in 1960's Israel - and forging a friendship while sailing the troubled waters of deciding futures, bending cultural restrictions, falling in love, discovering that people might not be the ones you believed them to be... the usual growing up stuff that hurts so much at the moment.
The most similar of our past suggestions is Towelhead (2007). Turn Left... is a much milder version of the cultural and sexual tensions, though. Sara and Nicole - the central characters of Turn Left... - are almost grown-ups themselves and in position to negotiate their lives with much more agency than little Jasira, despite the fact that the time and place depicted is supposedly so much more conservative.
Plus points are gained with:
- Scene of female masturbation (still too rare in movies).
- Depiction of a close friendship that's intense and sensual but does not enter the territory of a full-blown romance. Romance is good (see Show Me Love (1998) for that, by the way), of course. Nevertheless, there's a whole vast area of attractions and intimacies that happen in friendships that balance on becoming a love affair but never get there, and it's nice to see them depicted in cinema.
