Why does it feel like the vast majority of lesbian characters in shows and movies are white, thin, and conventionally attractive?

Obviously, there are some amazing movies and TV shows that have BIPOC main characters and other diverse representation. However, it still feels like 80-90% of lesbian characters in more mainstream media have a very certain look. Is this just me? I can't actually think of a movie or TV show with a fat or plus sized lesbian character. There's only one series I know of with a physically disabled lesbian character. I would love to see more fat lesbians, masculine and butch lesbians, black, indigenous, and brown lesbians, lesbians who are disabled or who have some kind of physical difference, etc.

P.s. if anyone has recommendations for TV shows/movies with diverse representation, please comment!
