Hell, in retrospect... a huge, early plot point in my debut novel, Fadeout, is that the first protagonist was so disgusted with their actions as an officer of the Protectorate Navy that they semi-faked their own death- and wiped out their identity, all the way down to their gender.
Some of the crew get confused over who or what they are and eventually just take to calling them "the Captain."
Another character is a cis, heterosexual, tomboyish woman who is so mistreated by fellow crewmen on her previous ship that she feels like she's forced to crossdress as a boy to avoid it.
At the time I wrote my first incredibly cringey draft of what would later become my main fictional universe, and the subject of tens of thousands of words, I still identified as a heterosexual cis male.
Now I'm a bisexual, nonbinary femboy.
How things change...
