What does it feel like to have an "innate sense of gender"?

It has always fascinated me that some people "just know" what their gender is and have even known since a very young age. I started questioning my gender a couple of months ago and have had an incredibly hard time figuring out what my identity is without relying on what I like/enjoy and how I like to present. People talk about identity and expression being different, which I agree with. But, without those things, I don't feel like I have a gender identity and I don't know how "normal" it is to not "just know" what it is. I've always had a lot of frustration with my AGAB, which is what got me questioning in the first place. There's times where I feel masculine or feminine in a way that feels really good, which I'm assuming is gender euphoria. I'm also deeply jealous of androgynous people 🤤 in a way that I can only assume is gender envy and I get depressed/disgusted when my body looks too feminine or too masculine. The words "man" and "woman" feel equally weird and pronouns all feel the same to me. Are those things my gender identity??? I've been identifying as nonbinary since I started questioning and I'm terrified of coming out to someone irl only to find out that most people feel this way and everyone is just begrudgingly going along with the gender binary like I was. I really wish I could ask cis people this question, too, but I have no idea how to broach the subject with them without them getting weird about it. If only there was an r/askcisgender lol
