I've only danced twice in my entire life and I really enjoyed it BUT I can't help but laugh the following morning at myself. I just punish myself by imagining how weird I must have looked. But tbh, while I'm doing it I really couldn't care less what others think. I had always refused to dance and I have quite frequently remained motionless on the dance floor while others around me went crazy lol. But I decided to do it when this girl literally dragged me onto the dance floor. But clearly, girls prefer guys who dance, and who dance quite well. I admit it I suck, but I haven't given up on it yet. I would suggest just look at how others around you dance. If there is somebody who really catches your attention and you say to yourself, like I often do "I really wish I could dance like that" don't copy them exactly but try and get the same kind style. Then switch again to something else as probably variety would get the girls more interested in you. Just a hunch.
