Metamorphosis (2019)

Born with both male and female genitals, but raised like a boy by his conservative family, Adam goes through all the things prepubescent boys go through, including a fascination with strange animals he takes for pets and being smitten by a lovely girl. His bucolic world turns upside down when he gets his first menstrual period setting him off on a journey that tests the spiritual and physical limits of sexual identity and into a new world of ambiguity and desire.

Unfortunately the movie Metamorphosis is not yet available on HBO Max.
