yes, for a lot of girls.
I would know within the first 2 minutes really. But then it all comes down to if you like them in the long run.
Its only a superficial word
It was for me. I initially decided I wasn't gonna have sex with my boyfriend the very first five minutes of meeting him, but after the first like month of dating definitely changed my mind. It's different for people but personally I think that yes, the majority of girls decide whether they're gonna have sex with him.
