I love the fun you have with erotic innuendo and double intent. We do not know it is a "dance" until the end. My sense is that it is a dance of possible love-making and not a Tango or such. To me, the music being inside the woman feels much better than it coming from a venue.
I know this is gonna seem off key but I believe in feminism. Throughout this piece it seems it's you who are in command, refusing to take a subservient role despite the (apparent) cajole. In the end it is you who decides when it will end. This is gonna seem off key further but a mans gotta know when to let go. Although unabated I would have a tendency to carry on even if I were pretty much done if the woman still wanted it, nonetheless of we (men) lessons of history owe women this. They need to be able to feel that they are in control. Just like black people need their liberation, well, what was it my college girlfriend said to me "Women are the nigger of the world". Women's rights are something new to our prospectus, they still need some affirmative action here and there.
