Non-physical traits are psychological in nature...literally all in your head. Some days I feel "boyish" based on boyish norms, but that is a condition that changes, and in no way implies I'm an actual boy. Trans community keeps confusing the issue more and more by introducing absurd terms like "fluid" which basically mean absolutely nothing since it's just whatever they feel at any given time. At least my gay friends are being honest about their preferences. Even they can't stand to be around some trans people.
