How have gay men interacted with and regarded lesbians, and vice versa

Would like insight and education into the various ways that gay men -- both as individuals and as a group, both historically and currently -- relate to, regard, and interact with gay/lesbian women, and vice versa. [I've tried to be thoughtful in my wording, but I've not had all that many occasions in my life to discuss LGBT topics. So I'm nervous that I might misspeak or expose my ignorance. If I do please correct me and accept my sincere apologies.]

Looking for in-depth readings and histories and seminal texts that would give a good overview of these group dynamics. I'm most interested in learning about the U.S. in the 20th/21st century, but if there are pieces that also address this dynamic in other cultures or other times, then all the better.

My (uninformed and simplistic, and possibly irresponsible) perceptions -- and here is where I'm afraid of sounding like an ass -- are that while the two groups have had every reason to form a coalition in the ongoing struggle for their safety and their civil rights, it doesn't seem to me that there is all that much overlap in their various subcultures' interests or arts or patterns of consumption or recreation -- it just doesn't seem like they have that much in common outside of their shared struggle.

Looking, also, for feminist critics' assessment of any patriarchal systems at work within the gay/lesbian cultures.

I know that there will no doubt have been a spectrum of opinions and a healthy, ongoing internal debate; I'm not afraid of readings that address or embrace this complexity.

Are there seminal works addressing this relationship? Great essays? Contentious works of art or fiction? Watershed academic studies? I'm very willing to read long-format or challenging pieces.

Many thanks... and again, please, please correct me if I've said anything ignorant; I'd consider it a huge kindness to me if you would.
