So I'm autistic and can't read signals.

But I can sure read when a girl makes her voice higher pitched and plays with her hair. Does anyone else have other signals of interest that help.

Last week I was getting to know a girl and I was being awkward until I changed my mindset from cute girl to another friend.

What I need to get better with is physical contact, I tried to escalate a bit and she didn't flinch so I think I'm reading the signals correctly.

Any thoughts or tips on how to read signals and improve physical escalation?
