Sexual desire and its manifestations are difficult to discuss, in part because of the conundrum created by feminist shallow-thinkers, as opposed to deep-thinkers, like ‘a little knowledge is dangerous’ type thing. Viewing a phrase from a song without giving credence to its complexity is to misread it entirely.
The song at its core is talking about the all-consuming desire for connection with another person and how that manifests as a sexual and physical force, even in the absence of the other person’s physical presence.
Now to feminism. On the one hand allowing for freedom of sexual expression, using terms and ideas like ‘little girl’ and ‘daddy’ is just fine. However, a sloppy understanding of sexual freedom would say that such roles are bad for women as they reinforce infantilism and lack power for women.
So how to balance sexual freedom with the idea that doing what you desire is damaging to women? If someone wants to be called a whore and spat on doing sex, that is up to them. Should they stop wanting that because it is damaging to women?
I think we can safely say that the song is not a pedo song, however.
