For awhile now, I've felt that being "female" (I'm AFAB) doesn't really have any significance to who I am. I don't feel dysphoric being seen as female, but I don't feel it's at all important to my identity and who I am as a person. Also, despite not being uncomfortable being referred to as female, I prefer to refer to myself and be referred to in a gender-neutral way. I've questioned whether I'm cis (due to the lack of gender dysphoria) or nonbinary (due to not feeling any strong connection to being "female", or any other gender, for that matter), and I've determined that I'm probably nonbinary but fall somewhere between cis and trans (since I don't consider myself female but also don't consider myself to be any other gender).
I came across this article about being agender on the Gender Wikia last night, and agender seems to be a term that fits me. I've underlined the parts that describe me:

I don't intend on fully "coming out" until I'm more certain this is what fits me, but I do have some questions about it. I know that transmen and transwomen have a fairly high risk of being rejected by family and/or friends when they come out, being told they're "wrong" for identifying as the opposite gender, not having their gender identity respected, etc. What about people who are agender, though? I definitely expect some people to not understand it's even possible to be anything other than male or female and still just see me as a girl, but, realistically, is there any significant chance of facing any particularly negative/hateful responses or rejection from anyone? If so, does anyone have any advice for coming out?
By the way, I'm not afraid of my parents disowning me or my boyfriend leaving me. I wouldn't be surprised if my parents don't understand and still see me as their "daughter", but they're pretty supportive and caring, so I doubt they'd respond in any intentionally hurtful way. As for my boyfriend, he already knows I'd prefer not to be seen in a gendered way. He doesn't seem to quite "get it", but he did tell me it's good that I'm at least trying to figure out my comfort zone.
