yes, it wasn't until I transitioned and read all the studies about shared genetic causes of gender dysphoria and autism, and the high overlap between the two that I finally took seriously the feedback I had been getting my whole life that I might be autistic - so my own proprioception issues might also be linked to neurodivergence. Estrogen seemed to help a little bit with my proprioception, but I am still clumsy and my spouse has noted that it hasn't been fixed by transition.
I do feel like you that my body just feels too large, and I do think that's part of why I run into things - the hormones haven't fixed that, so maybe that's a life sentence, unfortunately. And "damned flesh prison" is pretty much how I would describe my body since I was maybe 15 - 17 years old? But hey, still cis tho.
