Female homosexuality in the early 1980s. Anybody know anything about that?

I've searched through my library and used my meagre Google-fu to no avail, so I'm putting this out here: Does anyone know anything about female homosexuality - attitudes about lesbians from straight people, attitudes about lesbians from lesbians, culture, dress/mannerisms, etc. - in the late 1970s to mid 1980s? Keeping in mind, the characters I'm juggling are working- to lower-middle-class women in rural areas who wouldn't be involved (or possibly, even all that aware/concerned with) the women's movement or the gay rights movement, and who come from close-knit, probably conservative - but not necessarily Christian - families. They're probably not going to be "out" in any way, and they're staying in the above-described communities, not moving into places with a gay... er, area? Scene? Whatever, you get it.

Also, bisexuality, particularly female bisexuality. What was happening with the attitudes towards that, both within the gay community and the larger society? I know this was the beginning of the bisexual backlash among the male gay community, but information about female homosexuality is (unsurprisingly) sparse, and female homosexuality outside of the context of the lesbian community / gay rights movement / women's movement is even sparser.

Meta or personal experiences welcomed with gratitude, but I'll also take recs for any movies, books, tv shows, or pretty much anything else you can think of that's relevant and set in this period. (Thanks!)

This is probably the dumbest thing I've done all... day.

I am getting into a fandom that rates things G, M, T, and where half the fic resides in the Pit.

Oh my god, kill me now.
