Where does it say she’s a lesbian?

People don’t seem to understand yet that trans isn’t a sexual identity. It’s a gender identity. She could still be attracted to men when she was a trans man, she’d just be trans-gay. Yes, that’s a thing, and a quite common thing among “trans women” (male feminists in drag) who still are attracted to women.

This isn’t a scenario where she was a lesbian and decided it was because she was a man, those thoughts are usually independent of each other.
