I honestly don't know, this is one of the greatest dilemmas I have. I'm 6'1, I have a very broad build because of genetics and lots of heavy physical work from a very early age. I'm 22 now, had big downs, put on a bunch of weight I shouldn't have, and quite honestly, unless I have a very optimistic day, I just can't see myself passing or being gendered as female by anyone. I'm still planning my transition, solely based on the facts that there are tall girls out there, there are broad girls out there, there are overweight girls out there, and as it's been said before me, if I can be a girl, even an ugly one, it's worth it. But if it's strictly down to passing, then yes, I need to pass, otherwise it doesn't seem to worth it.
