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?
Well I don’t really worry about anything, I’m fine with how it is :3
But a question which does arise reading this answer is: If most people don’t have a feeling for gender, why does gender even exist in the first place? I view gender as a set of personality traits that are summarized under one term (a gender). If you match the personality traits connected to a certain gender, you have this gender. This makes it easier for people to have a basic overview of your personality without you having to explain much. But if most people actually don’t really correspond to gender norms and don’t have a feeling for their gender, doesn’t gender cease to exist? Isn’t it just your name and your pronouns at this point?
E: I know that gender and sex were (partially are) considered to be the same. It’s more a theoretical question emerging from the current view on gender, I know that patriarchy and stuff prevent immediate practical effect.
Patriarchal control mechanism
Gender and Sex were synonyms up until very recently, and many people still consider them synonyms. Gender was the ‘nice’ way to refer to one’s sex.
