I decided to take a challenge with this list. I feel there should be representation for people who are asexual.
A character is not sexually attracted to men or women and/or not interested in having sex, and the lack of sexuality is not celibacy. They don’t get ‘cured’ at the end.
Suggestions would be helpful. I’ll watch and then add them.

Movies I find iffy:
PK
Pee-Wee’s Big Adventure
Amelie
Birdy (1984)
The Nun (1966)
Brave (2012)
A Heart in Winter (1992)
Repulsion
Watch Out (2008)
The Purple Rose of Cairo
No Men Beyond This Point
Antisex (2008)
Withnail & I
Marie Antoinette (2006)
Liquid Sky
The Elementary Particles
Carrie Pilby
Nymphomaniac I

Rewatch needed to be sure:
Mary Poppins
Sleeper (1973)
Shoplifters (2018)
My Fair Lady (1964)
Hamlet (1996)
Shortbus (2006)

I discovered two of these movies thanks to kylreisner’s own list on here.
