@mindpersephone I have.
I've felt sufficiently detached from gender (and especially from cultural expectations of performance thereof) that the idea of being some form of cisn't has crossed my mind.
And I think the answer is "I'm autistic and cis, and very much in that order, and may perform gender nonconformity as a direct result of this."
Specifically, I got married in a corset and circle skirt made for me by a friend solely for my sensory desires of Squish, Swish, and Shiny. The circle skirt material was a metallic blue fabric I couldn't stop stim-staring at in the shop where I met said friend to be measured, so we chose it; meanwhile, the navy taffeta corset was made not for body-shaping but for even deep pressure, and it helped ground me on the big day.
I have wondered what it would be like to not be a man, and it's not felt right. But I'm not attached to this one either; I just haven't really felt dysphoric either, and the alternatives (plural!) just feel at least as ill-fitting if not more. So I've called myself "inertia cis" 😂
