Some traits may not be too obvious but yeah stimming is a defining trait of autism but maybe your stimming is different i dont know im not a doctor i had difficulty telling if i had sensory issues so thats why i ignored my autism.
This site is great it has a forum i dont know how active it is sometimes i think i may join it again.
I went on 2 dates with women I met on an online dating site, this was way back in the late 90’s and early 2000’s. Both relationships went nowhere, their profiles made them out to be more attractive and interesting than they were in real life.
