I took my girl out clubbing yesterday and had fun. I can't dance smooth at all, in fact, I always joke w/ girls that I only got one move on the dance floor.
If you can't dance, just bounce or 2-step, and don't go apesh!t looking like you're having a seizure. Also look around and you'll find that over most the people on the dancefloor can't even dance, and this includes the ladies. in fact you'll notice, if someone actually looks good dancing, everyone around him will stop and watch.
also, if you're afraid that your girl is gonna get hit on, just remember if she's good-looking, she's gonna get hit on by random guys from now until she's 30 or 40. no way you always gonna be around to police her so if you can't trust her now, then drop her
on the otherhand, if you go to the clubs to practice your game.... never bring sand to the beach haha
