It's a risky move, but you are probably revealing too much about yourself... maybe It's hard to say when we don't know the relationship or the person.
I'm trying to take a tip from comedians, I am going to disclose more 'faults' of mine very early in a conversation... but do it in a self-depreciating funny way. The key is to isolate your weirdness and make it know to the other person that you are aware and it's okay. Perhaps in an advanced form, you could use this for flirting.
Autism is a trickier thing to explain, it would be better to focus on the symptoms instead... the ones that people can kind of see...

Wonder what it feels like to be in love?
How would you describe it, like a push or shove?
Guess I could pretend that this is all I need
Wanting more than what I have might appear as greed.
