hi let me tell you all a secret
i'm transmasc and also a lesbian. i consider myself butch. i'm in a relationship with a wonderful girl who is also a lesbian, and we joke about being yuri occasionally.
my pronouns are he/him, i have a beard and a deep voice, i've had top surgery, and to the general public i appear to be a cis man. i like it that way! i believe this aesthetic is as far on the butch side of the butch/femme spectrum as you can get. men, even cis men, can be butch. it just happens to be the default for them due to cultural expectations, so we don't generally think of it like that.
i never felt quite comfortable with the gendered expectations of being in a straight relationship. i've been reading yuri since i was a tween, and back then i considered myself a lesbian too. once i realized i wanted to transition to male, i thought i had to let go of the lesbian label, even though i didn't really feel straight. i even felt guilty and creepy for reading yuri, so i stopped doing it for a while.
i've always related to lesbian romance more than straight romance, so i decided to not let go of the lesbian label for myself. i'm also very lucky to be dating such an understanding girl that can look past my flesh shell and love the real me inside, and our love is very gay, despite appearances.
this may be a rare story, but it is real! yuri, yaoi, gay, straight, man, woman, they're all just words we use to imprecisely attempt to describe an infinitely complex reality. all words are like that. we made them up to create pretty much arbitrary dividing lines, and now most people insist on following those lines to a T. even though many people don't even agree on where those lines lie!
the truth is, words are fake. but love is real. self expression is as fluid as the blood in our veins, and true identities are as numerous as individuals.
and while yes, words are useful as a tool to communicate, they should not be mistaken for the reality they attempt to describe. the beauty of a tool that can change is that you can use it however you want. i will respect your words, and i'd want you to respect mine too. we can use different words to describe the same thing and still agree. there's no point in us telling each other we're using the tool wrong, as long as the job gets done.
what i'm saying is we should all take this stuff a little less seriously. describe yourself however you want, and i'll respect that! you can do whatever you want forever. but in a queer and open minded world, nothing and nobody are exempt from potentially being yuri.
