If you don't feel comfy dancing at clubs and shaking it fast, maybe start out in your own surroundings with friends. Every weekend or so my roommates and I just turn up the stereo in our living area to "work what our mama's gave us". If you start out in the privacy of your own apt. you might feel more comfortable. We also go to techno clubs sometimes and with the music going and the crazy techno lights, it looks like everyone is moving in crazy directions.
