How the hell are you supposed to 'push' if you're sitting at a bar right next to someone without it feeling like you're trying to run some pathetic mind game on them? Or would push be a slow down or reversal of escalation - maybe breaking physical contact for a bit?

Bonus question: If things are going pretty well, would you ever end the date so they're even more exciting about seeing you again, or try to have sex with them that day or night?
