Sexuality, gender, gender expression, gender identity, these are all so fluid. You define yourself however you like, and if you want to define yourself. Or you can just say "->-bleeped-<- it" and be yourself, and not give a sh*t what anyone else thinks.
Now, if you try to explain this to other people, especially those who like to categorise people into little boxes with clear, concise labels, you're going to get some weird looks and a few "But I thought that X means you're Y, and that Alphas are never Betas, and blah blah blah." There will even be, "No, that's not right. If you're X, then you act like Y. End of. And I know this because I know a guy whose friend's cousin's college roommate's sister was X, and she acted like Y."
Ugh.
Just do what makes you happy and harms no one.
