When I was younger, I thought I was the 'opposite' binary gender to my assigned one and expressed myself accordingly. I was asked if I wanted to transition (in their words "have a sex change" when I was older. I replied no. Scornfully. Why would I do that? How would that even work? Such was the cis filter on my life that to me, at the age of thirteen with a lot of gender-related Feelings, trans people were the crossdresser in the charity shop in town and the 'tranny' comments people made when they saw me. I had no idea that these genitals did not make me my assigned gender, that there was a possibility of not being my assigned gender, that there was a whole world outside the binary.
