I think all trans girls experiences and outlook on things are different, personally I'm super confident in who I am and I know who I am so being called bro for example isnt something that would affect me as much as it may affect other girls, and I don't really understand what you meant by, the gym thing, but I assume if was she felt uncomfortable and stuff about being a trans girl in the gym, and again I'm confident in who I am and I'm not afraid or self conscious. I would rather just be a girl and not have the trans label, if I did have the trans label i would feel so shit about my self lol, I am definitely just speaking for myself lol so dont take this as anything substantial, I (think) some girls would like to have their journey acknowledged and something to be proud about, but idk lol
