Welcome!, from another newbie.
I have a few comments relevant to what you said. Various factors kept me from figuring out that I had AS until last month, at 51. And I seem to be somewhat atypical, even for an aspie.
Even if you accept my self-diagnosis, I admit, I am only one aspie. My comments won't fit everyone. But I can tell you this: the outward signs are there, but what the "experts" claim goes on inside? They maybe have it half to three-quarters right, distorted, through a fog.
Why am I so sure that I am an aspie? Well, this is the first time a whole string of puzzling things in my life have finally made sense, looking at it through that lens. I even found another aspie on here that has the same trouble I have doing anything that requires rhythm - something I could never understand or explain. Big picture, little details, this is the only time it has all made sense. My eye problems (legally blind) and all the ripple effects from that, my strange childhood, my ADHD, I assumed those were "it", but they never came close to making sense of it all.
So what's my point? Well, if you view yourself as an aspie, and things make sense that didn't before, then you probably are. Don't assume the experts are always right; after all, the experts thought the Titanic was safe enough to skip installing enough lifeboats... And I have a suspicion, from what I've read, that AS tends to appear a bit different in women. Those are at least things for you to think about.
