Historically, pornography has been used more often by straight men to look at women than vice versa. As such, as pop becomes more pornographic, it is the girls’ clothes that come off more so than the boys’. Likewise, there is a strong tradition in pornography of straight men enjoying girl-on-girl scenes, a tradition not equally matched by women enjoying gay male erotica. Thus the rise of female bisexual imagery in the music industry is directly linked to the pornographisation of pop: as straight men enjoy girl-on-girl action in porn, we see a softcore reflection of this all over pop culture. And as many female porn stars take such work where they can get it, regardless of their real sexuality, it seems many pop stars do the same.
I’ve always thought “I Kissed a Girl”—despite being extremely catchy and fun to sing along with—was exploitative.
