Thanks to the Rev. Bob for the link to this photo, which he left in the comments. This illustrates one of my points: Males and females often are posed differently in photographs, with the latter made to look vulnerable. That's one reason we laugh at this photo. What does it say about our culture that attractiveness and sexiness are often linked to vulnerability in females, more often than in men?
In the original photo, Miley is posed as if she has been caught unaware and holds a sheet to her body in modesty. Why is that sexy? Because we like girls to be modest, yet available? Because sneaking a peak of a naked girl is more exciting if she doesn't want to be seen?
Ms. Magazine's spring issue has a review of Gigi Durham's book "The Lolita Effect: The Media Sexualization of Young Girls and What We Can Do About It." The book suggests ways adults can teach kids to deconstruct stuff like Miley's photo shoot.
