You know now that you mention it, the internet makes me believe that there's a vastly larger amount of trans women than men, but I too only know trans men directly. I do wonder what the proportion is, if it matches whatever the ratio of men to women is. I also wonder what percentages are when you consider enby people and what those numbers do to the overall percentages.
Obviously the numbers are skewed by people who can't be open about for one reason or another, but still curious either way.
