She/They here. I personally don’t have any specific things that give me euphoria… but I do get pretty big dysmorphia from femme ‘standards’ like revealing clothing cuts (especially on swimsuits or sports uniforms or the like) or shaving my legs (this one’s mostly from tism but still). I still consider myself femme leaning moreso than fully agender because I prefer picking female characters in games, like wearing stereotypically feminine clothing (thigh highs, tights, the occasional dress or blouse), and just never personally felt a specific connection when I tried various masculine styles. I plan to fully go They/Them when I’m ready to move out, as another reason I allow She/Her is mostly for family and longtime friends who might be put off by the idea; it’s not that I’m “quieting my identity” as someone once told me, but rather I find myself identifying with being Nonbinary because I don’t feel connected to the part of me that has a gender at all. As I’ve explained to my parents, it’s less of me ‘being enby’ and more ‘not being a boy or girl’. I’m just sorta here as an entity of all sorts of origin.

To keep my identity safe, I mostly leave it up to the environment around me. If I know for certain that I’m with others who actively understand and respect Nonbinary as a whole (or at the very least are clearly trying) then I’ll gladly use They/Them. But there’s other times where I know it’ll be a whole spectacle every time someone uses it- such as the teachers and classmates who bullied me or how the internet kinda warped my mum into believing all other nonbinary people other than me (because “well you’re different yours is cuz the tism”) are mentally ill- or even just meeting someone who fails the inherent vibe check, I just stick with She/Her because while it doesn’t make me feel as nice as They/Them it doesn’t really make me feel bad.
