How do women identify sex havers so accurately?

I was coming up on a two year dry spell and then I got laid a month ago. It was nice and definitely boosted my confidence. And last night I pulled a girl on the fucking subway. Not even in a bar, on the subway. It's crazy how much easier it gets when you have the aura but I have no clue how women detect it. I don't feel like I was acting any different and in any case I was about a beer and a half away from blackout drunk. It's like a superpower and I almost resent it even while benefiting from it.

edit: since this post has done well i want to add the detail that she was german and gave the sex a rating out of ten afterwards lmao
