Hi:
There is possibly another aspect of the question you raised if that's what you intended: Whether you are legally recognized as living in the gender of prefer depends upon the legal jurisdiction you find yourself in when the question arises. It's not a simple answer, blanket answer as you might imagine.
If this was part of your question I would suggest you Google transgender legal status + the circumstance(s) you are concerned about, e.g. marriage, passport, medical status, etc. I wish it was simpler but at this time it isn't even simple across the USA, often intrastate, and in extreme cases some foreign jurisdictions there may be serious prohibitions to be concerned about.
Best to know than than be unawares.
TTFN,
Rachel
