YES! I constantly slouch. It feels unnatural to stand up straight.
When I force myself to stand up straight, I have to constantly think about my posture or else I settle back to my natural "wilted-leaf" stance.
When I was younger and learning how to properly sit at a computer, they instructed us that sitting up straight was best. I didn't think anyone really sat or stood up straight in real life. Since it was so uncomfortable to me, I thought it was for everyone else too. I thought it was just a health thing that we should be doing, but not something we actually did normally.
However, I began to notice, (much to my confusion and fascination), that many people do indeed naturally carry themselves like this.
Maybe this is a low muscle tone thing common in ASD. I am pretty floppy.
