I have a really early version of Lesbian Couples by Merilee Clunis and Dorsey Green, which I picked up in a used bookstore because I find [relatively] old advice books fascinating, especially when they have to do with queer people.
I expected very little from this book, but was pleasantly surprised to discover that even the first edition was surprisingly down-to-earth and practical. It spends a lot of time discussing how feminine enculturation, socioeconomic differences, race/ethnicity differences, disabilities and illness, age, fatness, outness, feelings about one’s body, familial opinions, etc., etc., may play out when women are involved in relationships with women. It offers standard techniques for respectful communication and listening with an acknowledgment of how the aforementioned factors may complicate them for women. It’s very matter-of-fact, unsensationalized and sensible. The clear, calm writing style, combined with its mostly successful efforts to include people with a wide range of identities, makes it a refreshing change from trendy, narrowly targeted bullshit [‘s’up, Rules series?].
Anyway, I see they updated the book after about 20 years. ^_^
