i used to be the same way i would stay away from the dance floor if i ever got kidnapped and thrown on one i froze. i usually stood away just watching but man i missed out. i love dancing now. as long as your having fun thats the biggest thing....another thing is if its a club its gonna be dark and loud nobodys is gonna notice what you are doing anyway. but mainly just be yourself and have fun. depending if you prefer a certain club only find out the type of music they play so you can learn a few dances to get yourself in there ( cupid shuffle, cha cha slide, electric slide, etc.)
