Gynosexual
Attraction to femininity, whatever the person's gender.
Gynosexual describes attraction to femininity and female-presenting people, without assuming anything about their gender identity. A gynosexual person might be drawn to women, to feminine non-binary people, and to trans women alike.
The word exists because older labels tie attraction to the gender of the person feeling it. Heterosexual and lesbian both require knowing the speaker's own gender first. Gynosexual describes only what someone is drawn towards, which makes it useful for people whose own gender is non-binary or in motion.
Its counterpart is androsexual, for attraction to masculinity.
