I’m an old cis/het dude, and while I’ve occasionally fantasized about being a woman, it was entirely out of fascination with something else - not identity. I don’t necessarily ‘feel’ male, but being female is incomprehensible to me.
Compare that with a dear family friend. When they were about 13, they announced that they were nonbinary; and two years later, decided they were transmasculine.
What was their trigger?
While presenting as nonbinary, they naturally got mistaken for either male or female. They realized that being mistaken for male was totally cool, but being mistaken for female hurt terribly. They identified with being male, and being female (their AGAB) felt abhorrent and wrong.
So if you don’t have some part of your brain screaming “NO NO NO!!!” at you, you’re likely an average, 21st century cis person whose ability to access infinite porn has dulled your sexuality a bit.
So don’t worry too much.



Most English-spealking people outside the US said ‘aught’ instead of ‘oh’, but definitely about 2005 the ‘two thousand and’ syntax evaporated.
