binary trans or genderfluid?

It's entirely possible, or perhaps you're bi-gender, which is like genderfluid but with only two distinct genders. Genderfluid usually involves 3+ genders, which can include any binary or non-binary gender such as agender, demi-guy, androgyne, etc.

I am AFAB, bi-gender, and I experience distinct male and female phases. When I'm guy, I'm all guy, when I'm a girl I'm all girl. Both fully binary. When I "settle into myself" (zen out, meditate, whatever) I know which one I am. Sometimes both genders are there at once, but distinct, I can identify both, two separate and distinct feelings, almost like two separate persons. A girl version of me and a guy version of me. It's not entirely unlike "multiple personality disorder" except that I don't stop being *me* when I switch, my personality doesn't really change at all, I just have different feelings and motivations that come from within.

From the time I realized what was going on, it took about six months of introspection and therapy to really understand and be able to distinguish between the part of me that is a guy and the part of me that is girl. Once I figured it out, they became even more distinct, and settled into a pattern - I get 3-4 months of each before switching, and there seems to be no rhyme or reason to when I switch.

When I'm feeling girl, I feel totally and entirely like I'm a cis girl and actually start doubting I'm transgender at all. I adore skirts and dresses, sparkly things, painting my toenails, and I adore my dangly earrings and other jewelry. I feel better about my gender identity as a girl, more completely girl than I ever did before I figured out I'm non-binary transgender. I used to be confused because I couldn't figure out why "I wanted to be a girl" when I was AFAB. I never felt I *was a girl* - something felt incomplete, or in the way.

But then when I feel like a guy, I feel like I'm all guy, 100% and my interest in girly things fade. I stop wearing earrings, I can't imagine why I would ever want to wear them. At some point I start to doubt I'm non-binary, I begin to believe perhaps I'm fully a binary transguy and should fully transition (I'm 16 mos on T, and had top surgery a month ago), I can't see or feel the girl anywhere inside, I only have a memory of feeling great about being a girl, and confused because it seems like such a foreign concept, because I'm a guy.

So look deep within yourself. Is it simply a lack of dysphoria at the moment, or it is a true feeling of self? A broken arm doesn't hurt 24/7, but just because it stops hurting for a while, that doesn't mean it's not broken, and the pain will return if you hit it wrong. Perhaps try on the non-binary identity for a while, explore to see if the side of you that is happy as a girl is real, or just a day when it's simply not painful. On one of your girly days celebrate your female side and feel it out. Does it feel right? It is you?

(A personal opinion only!) In opposition to Hawk's hypothesis that non-binary is merely a step toward binary trans, I personally believe that a large percentage of trans folks are non-binary to some degree, and are pressured into "nuking" any remnant of their birth sex, and lots of non-binary folks are living as binary trans, denying a part of their true selves due to peer pressure and strict historic "transition rules" created during the dark era of Harry Benjamin.

You are the only person who knows, and it will take time and introspection. Good luck.
