Another thing to add to this: Watching people interact over the years has led me to believe that it's a "boring" dancer that you don't want to be; women are attracted to the confidence and self-esteem required to dance when you suck at it.
Not only that, but if you're remotely musically minded, you will get good very quickly if you enjoy yourself. I never danced and was awful at it until I was 18 and started going out drinking and dancing with one of my good mates who shares your opinions on the liquor, but not the dance. He's a dancing machine, and it rubbed off. Nowdays, I can attract a sizeable posse of buff half naked gay guys during the morning hours at a rave, which is pretty good for a fat bearded straight guy :)
