Worrying if the quality of health care I receive will be affected because the medical professionals will be distracted and caught off-guard when they don't have experience with trans people, at least on a subconscious level, even if they have the best intentions. Or worse, that they will be disgusted and provide sub-standard care.
My primary care doctor is fantastic, so I don't mean that, I more mean in an emergency setting, or if I went back to the south where I grew up, or had a problem when travelling to another country or something.
