Honestly, the way I see it, "man" and "woman" and "binary" and "non-binary" are just societal labels... best-fit words that try to shoehorn everyone into narrow boxes.
Just like there's cis FAAB people who don't want breasts, there's also cis MAAB people who don't want their penises or don't want testosterone in their bodies. And the overlap with the trans community is a bit blurred.
What makes someone a man or a woman? Is a woman defined by breasts, or a vagina, or estrogen, or the social treatment they receive? Is a man defined by a penis, or testosterone, or his lack of breasts, or the social treatment he receives?
The only answer I can think of is, it's complicated. Because there are many women who don't have breasts naturally, or are born without vaginas or uteruses, or whose hormones are a bit different, and men who are born without penises, or who actually do have gynecomastia, and yet have no issues saying that they are women or men. Likewise there's trans people who don't want top surgery, don't want SRS, and yet have no problems calling themselves members of their identity gender anyway. Some trans people don't even want to get on hormones. So at what point do you call them trans?
Basically, at the end of the day, all this is, is trying to slap a nice neat label on a humanity that is WAY more complicated than can be shoehorned into a group with a label. At the end of the day, you are you. You know what you want. If you're happy with having had top surgery and yet still presenting as female, then that's who you are. To hell with what anyone thinks, and to hell with any label. Because at the end of the day, who cares? You're a person that's happy being you, regardless of what someone decides to call you or treat you as. So I wouldn't worry about it.
Like, let's suppose that it was completely socially okay to be male and yet be pretty, and that it was possible for society to treat men in the same way they treat women, as non-threatening, as sweet, as personable, as able to be emotionally close with people. Then would I have needed to slap the label of "female" on myself? What makes me female? Is it that I'm on HRT and happy, that I want SRS, that I speak in a high voice? Or would I be okay with being male if we lived in a society where it was acceptable for men to be treated in the same manner that women are treated, and have smooth skin, boobs, a high voice, and not have a penis anymore. Would I mind being seen as male then?
I don't know. It's all societal BS, and we live in an imperfect system. So I say do what makes you happy, and to hell with the labels. Labels are purely for the benefit of others who are trying to understand and categorize you, not for you. They're imperfect best-fit words. At the end of the day, I don't know if I'm "female" or not. Am I? Or am I just a man who's more comfortable with smooth skin, boobs, doing "feminine" things, and being treated like women are treated? I don't know. But who cares. In this imperfect system, calling myself "female" is the best way to get people to understand me, so I use it. Same deal with you and other non-binaries. At the end of the day, the label doesn't really matter, what matters is that you do what makes you happy and be proud of it.
