I just saw on TV a song, a nice song, where the male singer kept putting his hand on his crotch and push it a little bit up in a quick move. This is something not new and think you all notice that. But wondering, what is this supposed to be for? kind of seducing dance or what? Why did they even start this kind of dancing? I personally like to see some sex seducing in a dance, but not that particulare move .
