Transautistic

So, I want to use the term... But I don't see myself as 'supposed to have autism' nor wanting to develop it. I grew up with an autistic sibling, and developed a lot of their habits and speech patterns. I, because of that, feel safe with other autistics more often than I do with non autistics, and also especially with low empathy autistics due to my ASPD. It's a really big part of my identity and how I socialize, so I'm wondering if using the term in that way would make any sense, or if there is something more fitting.
