I'm completely new to hookup culture, which wasn't a thing in the former small town i lived in.

I'm just curious how someone goes from a date to hookup within a night -- like how do you even progress emotionally so fast? Or do you not (because hookups are just flings without emotional baggage to followup with??). And if i were looking to date long term, but a girl wants to hookup, how can i progress from there and not keep it as just a one night stand?

Any advice from men or women appreciated, for a straight male in his 20s
