So I (M21) don’t necessarily understand what game is or is supposed to be and all my friends tell me that they don’t know how to explain it

I’m just confused. I can make friends with girls super easy and especially if we have friend or hobby in common. I guess what they mean is idk how to talk outside of dates like im wanting more sexualy or romantically but idk what to do. Like what is flirting?

As an autistic guy could you try your best to give specific examples if possible of what could be flirting?
