I think I'm simply fascinated. Fascinated, again it seems, with the whole attraction realm. Specifically queer attraction and gender; gender roles, gender orientation, sexuality and attraction. This is all I'm writing for now, later on this will probably be a running theme in the story I've got in my head.
