I agree we are all on a sexual orientation sliding scale.
In this case, my ex currently says she plans on no operations, sees herself as non-binary female, so technically we would "seem" to be gay (if, in fact, we actually did get back together).
I see myself as more male than female, so we could also be considered sort of gay males.
Actually, we would both be non-binary male and female, except reversed. When I think back, that's how our past marriage was anyway.
But, in the eyes of observers we would seem to be lesbians because I do little to present as male beyond dressing androgynously, as I always have.
