The short answer: I can’t tell you. In a masterstroke of unhelpfulness, I have to tell you the truth: only you can decide if you’re trans. Even then, there isn’t a definitive test to find out. So instead of telling you if you’re trans, I’m going to give you a few questions to meditate on and some experiments to try out.
Gender dysphoria is a feeling of inner conflict between the gender you identify with and the body that you have. This is a really common thing among trans people (although not required to be trans). For example, I often wish I had narrower shoulders, a curvier frame, and no facial hair. On my rougher days I feel shame, embarrassment, or anger because I want to look as feminine on the outside as I feel on the inside.
