From what I've heard, you sign up. Maybe you're served chocolate covered strawberries and champagne. Then, you're taught a "sexy" dance routine by a professional dancer. And in an hour or two, it's over and you maybe leave feeling like, "That was fun (hahaha, sexy dance class)."
I haven't, to be honest. From what I can see, though, is that women want to learn how to dance "sexy" and my question is: Why? And more importantly: How?
