As a woman in a cis-trans relationship, I find this fascinating.
I have dated men in the past, but as of now I only date women. My girlfriend is a trans woman.
She identifies as a lesbian and only dates women, that includes trans women. She has no interest in dating anyone except women, including men and non-binary people. In order for her to be attracted, a woman has to have a certain amount of feminine presentation and identity. Where would we be defined in these new definitions, and would they fit us? I do feel we are in a lesbian relationships, that is what it feels like, yet we are technically different sexes (she is post opp though, so what some would call transsexual).

Perhaps we should redefine gay and lesbian to be same gender attracted. Or better would be same gender or sex attracted.
I don’t feel I am a lesbian, I label myself as queer, but I do feel my girlfriend and I are in a lesbian relationship. She is definitely a lesbian, but if we go by biological sex she would be bisexual as she dates both cis women and trans women.
I’m all for just getting rid of lesbian and gay titles and instead having woman attracted, male attracted, female attracted, female and male attracted, men and women attracted, etc. a person sexual preference should have nothing to do with their identity, ie, just because I’m a woman shouldn’t mean I’m attracted to men. Our own genders and sexes should not dictate what sexes or genders we are attracted to. Lesbian and gay mentions identifies the sex of the person having the attraction as if that should dictate who we are attracted too, when all that matters is that I’m attracted to women.
