Issues with proprioception (which is the same as kinesthesia or simply put body awareness) is a really normal occurrence with people on the spectrum, so much that it is one of the common criterias in diagnosis. It compasses body movement, force, position, speed etc. It is called the sixth sense and as we are people with sensitivities and differences in sensing, it makes sense we have differences in sensing our bodies too.
That is why it's so beneficial to many neurodiverse people to use weighted blankets, and be swaddled for example and why for us regulation happens through stims and toys as opposed to exercise which can be challenging. To my knowledge, NTs regulate mainly through exercise (and of course processing emotional things verbally but this is more about the body).

I have often been told that every day movements I do "weird" like running, bowling, cleaning etc. A part of it personally is issues with my spine and muscles but I think autism is a larger thing. I find also issues with a lot of body-movements, not knowing how much force to use, things slipping or throwing things accidentally too hard or touching too hard or softly and so on. With exercise I can easily hurt myself because I go too hard or the movements I do awkwardly and can't learn the way NTs seem to know how to do.
I also find myself frozen in a bad position for a long time and can't really move despite experiencing discomfort. Then again I have such back issues there aren't really any good positions so it is sort of futile to correct, the pain just changes place lol.
Mostly for me the annoyance is with things that require fine-motor skills. Cooking and art really take a lot of energy from me, they are always a struggle and that is frustrating because I enjoy them so much but can't often really produce the quality of work I would like to.
