ive been over this with ppl and its not my voice, pretty sure its my height, my shoulders, my face (my selfies are probably a lot more flattering than real life) and my short hair. i like the way i look so im not too worried about it but i wouldnt mind passing better. i mean there are a lot of people who "had no idea i was trans", i think its mostly bc i live in a college town in california with lots of queer and trans people in it so theres a lot more visibility here.
btw when im saying im getting clocked, i mean that people dont consider me cis, not that they call me a man. nobody really does that
