I am probably quite agender, as I have no intrinsic sense of my gender. I simply accepted my AGAB (assigned gender at birth) without questioning it. At some point, I realized that I don’t feel any connection to this gender, no feeling like other people have. I also don’t see it as something that influences my personality and I don’t apply to gender norms. I just don’t care about gender. (This btw. also makes it harder for me to understand people whose sense of gender is so strong that they even reject their AGAB, although I accept their feeling, of course.) So how do you “feel” gender?
As an enby who’s best described as “the polar opposite of an agender person”, I experience gender both intrinsically and extrinsically. Dysphoria is a good example of the former; I used to have a deep and profoundly uncomfortable sense of “wrongness” about my body, like the feeling of wearing your shoes on the wrong feet but for skin texture, body odor, the shape of one’s hands, vocal pitch, etc etc etc.
Extrinsically, I’m mostly seen as a guy, which can be irritating when it results in getting called “Sir”, or a pleasant experience when someone recognizes that I’m not one of the guys.
