I’ve noted that a number of trans people have found their sexual orientations unexpectedly shifting during the course of their gender transitions. I identified as a bisexual woman pre-transition but was always primarily attracted to men, so I figured that I would be basically a gay man after transitioning. But I’m non-binary which complicates labeling, and after some time on testosterone I found my sexual attraction was too complicated to define using conventional terms. So I now simply identify as queer.
