The article talks a lot about how male sexuality has a darker side and violence and coercion come in to play and perhaps is exemplified by porn. One of the examples she uses is the scene from Last Tango in Paris where Marlon Brando forces Maria Schneider's character to have anal sex... It gets a little meta when you look up that film on Wikipedia:
"I should have called my agent or had my lawyer come to the set because you can't force someone to do something that isn't in the script, but at the time, I didn't know that. Marlon said to me: 'Maria, don't worry, it's just a movie,' but during the scene, even though what Marlon was doing wasn't real, I was crying real tears. I felt humiliated and to be honest, I felt a little raped, both by Marlon and by Bertolucci. After the scene, Marlon didn't console me or apologise. Thankfully, there was just one take."
Just a passing mention : the scene is much rougher in the book, because he actually convinces her to fist-fuck him IIRC, so that they are both "raped".
