WAP specifically feels like an experiment. A female singer's equivalent to the overtly sexual hiphop. In music, and in video.
Anecdotal: Friends have acknowledged that they're more disgusted by it than the male singer's counterparts. I admit I am, too. And this is regardless of the particular singer's ability to sing/rap, or the lack thereof.
Artistic merits aside, the (uncensored version of the) song and the music video seem justly regarded as a feminist redressing of the balance (if men can rap explicitly about being horny and wanting sex, so can women).
I recognise that, and thus acknowledge the importance of WAP, but I guess I'm more conditioned to expect this behaviour from men than from women? And the song makes me realise, and possibly correct for it, down the line.
