Hi I’m non-binary and I read your FAQ. I actually have gender dysphoria and there’s a difference between being a non-binary trans person and someone who’s GNC.
I plan on transitioning and going on hormone therapy to achieve an androgynous look to alleviate my dysphoria, and I am also a transmed and an exclusionist.
First off, congrats on taking the steps towards medically transitioning. Dysphoria is a bitch.
There isn't any specific trans look that every trans person wants to achieve. Some trans women want to look extremely feminine, some want to look androgynous. Same goes for trans men. There was a short while for me where the best way to alleviate my dysphoria was to go for a more androgynous look-- although this was because trying to look masculine just made me look like a tomboy which made my dysphoria worse. Once I started medically transitioning I find I am a lot more comfortable to all types of clothes and styles. There are clothes I could never wear before that I enjoy now that I have no chest and some facial hair.
I am not going to tell you that you aren't non binary. I don't have your full story and it's really not my place. However, I do question the link between wanting to look androgynous and being non-binary. Since there are binary trans people that also want to look androgynous (and there isn't any set androgynous look either). I know I had a hard time for a bit coming to terms with being a man thanks to the toxic part of the lgbt community hating straight men. I never really considered non binary though.
I'm sure you've already put in a lot of thought about what it is your feeling and everything else. Which is how you landed on non binary. So I won't lecture you on that whole "make sure you want this cuz certain parts of medical transitioning can't be undone." But I am still skeptical about non binary due to the group as a whole treating being trans as a fashion statement and belittling trans experiences (same goes for non-dysphoric binary trans people). While there is the biological component of it, most of my issues come from the attitude of the community and the damage that it has done. But like I said in my FAQ, I'll still respect non binary people's pronouns even if I don't like the community or the way that people are using the term.
So thank you for sharing your experience--it's definitely unique. And I wish you luck with your transition! If you're afab and want tips on top surgery or T let me know.
