I'd turn straight for him.
Weird saying that considering....
Lesbian going straight for a hot well toned trans man. Sounds like the start to porn.
There is one thing of our society I don't get sometimes, that urge to classify it all.
Makes a lot of trouble as it puts up bordelines, people rally behind and defend them.
So without wanting to put words in your mouth I would just say:
You are a person liking other persons. Or not. Your choice
The reason I don't like that gender discussion is that it makes it all so complicated. Everyone is just who they are, no need to imprint anything on them.
That discussion still is necessary to get that thought to people I guess.
The only "must" in that is that for procreation 2 people with different natural presets have to come together. Even that is slowly going away as medical science already fertilized egg cells with female DNA. (was some time ago I read that, was afair animal cells, but the principle seemed straight forward.)
In the end, just love who you love. With only few exceptions (underage, mental status, the loved person themselves) noone has the right or moral standing to tell you not to.
