Many people find the donkey punch disgusting and misogynistic. That's valid. I also find using MySpace as a form of foreplay abhorrent. But the point is that no one in the adult industry who makes or sells porn gets to say so, especially if that opinion is alongside the word "boycott". You can't make a bukkake video and say someone else can't make a donkey punch video. You can't make a sex-positive couples' film and say it, either. Your definition of exploitation is just a little more stringent than someone else's.
Alex Devine has said that Steven French used a ring in Donkey Punch and that he was too rough. She asked him to stop and he did. Sources say he is rough with women. He should not have used a ring. He should have stopped before he was "really" asked to. There should not have been toe-sucking. This is Donkey Punch, for Christ's sake. Don't creep me out.
But engraved into the stone of Monticello is Thomas Jefferson's oft-repeated maxim that if you are going to show deep, soulful kisses between condom-only consenting adults after a lengthy dialogue scene dealing with pirates or vampires or whatever paunchy couples on sofas are watching these days, you can also show the Dirty Sanchez, Blumpkin, Cleveland Steamer, or Donkey Punch.
Don't buy it if you don't like it, don't do it again if you didn't like it the first time. All bets are off when you know what you're getting into.
