Dancing... fuck this shit

Never ever do I want to float like a butterfly without stinging like a bee.. How the hell do you guys get past the "lets dance" shit test?

It feels like you have to make all the moves that match her expectations in order to proceed to greater intimacy.. Why is is not sufficient to be aloof at the bar?

Any advice would be great as I suck at dancing and dont feel i should learn to be something I am not?

Kind regards

Edit Awesome response chaps thank you.. reading and digesting now
