it seems like all the recent (well, since i've been a member) threads on this topic have stayed pretty quiet, so i'm glad you started this one!
one of my partners is trans and butch. he's primarily attracted to queer femmes. i identify as a queer femme and have since before we met. we've never been "lesbian-identified" as a couple...he identified as a lesbian earlier on in life, i never have, and he was at the beginning of his transition when we first got together. he is still pretty early on as far as medical transition goes, having had to stop and start hormones and not having access to top surgery. we both are pretty involved in queer communities and have friends of all sexualities and genders as well. i would say, like julie, that "butch/femme" is probably the most accurate descriptor of the dynamics of our relationship
at least as we see it.
