"The vagina is becoming big business." This is not a story about sex work — it's about marketers talking honestly about female genitalia, and the fact that the AP is getting away with using it high up in their stories is basically case in point.
Marketers have taken a cue from Eve Ensler — that was fifteen years ago, by the way — and decided that they can shout "vagina" all they want. (Sometimes the frankness is ill-conceived. The ad exec who created the offensive Summer's Eve ads actually crows in the piece, "We're really excited about having that kind of publicity and coverage. A month ago nobody was talking about feminine hygiene...We just wanted to be sure that the conversation is focused on celebrating and empowering women." All I have to say to that is shut the fuck up, douche salesman. Isn't frankness fun?)
