Of course, that's fine, and I don't mind either way. I feel the need to lable myself has passed me by. I call myself female because I was born female. I also only ever had realtionships with men, but I have felt attracted to women before. No idea what the future holds, but whatever it holds, it's fine. I guess I mostly feel non-binary, as per your definition, though there are moments where I feel strongly male or female, too. It really makes no difference in the end, right?

ETA: Funnily, I own a stuffed animal that I identify as female but call "Mr Bear".
