Truth be told, the ability to dance isn't a woman's 1st prerequisite to choosing a man. It is only a factor if you hang out at bars, and if barflies are who you choose form relationships with. In my life, that doesn't seem to happen very often in reality, and of the people I know who met their SO's in bars, I can only think of one whose marriage has lasted, and most of them never made it even to the marriage stage. The couple of others I know who did marry, ended up in divorce- one of them because of alcoholism on the part of the man.
The ability to dance certainly is no measure of character or of other important factors in choosing whom to spend meaningful time with. It's only fun on a temporary basis, and that is when you're on the dance floor, and that is assuming that you enjoy dancing, which some people seriously do. I am just as happy bopping around here to Aretha Franklin by myself, or practicing ballet at a ballet barre, as I used to be back in my youth, when I used to go dancing. If I were a professional dancer, I'd probably care if my SO could dance or not, but that would be more a matter of shared interests, than anything else.
