You're ashamed by how much you love watching femdom porn aren't you? Maybe it's the cost, maybe it's the guilt, maybe it's because you feel like it's 'wrong'. Perhaps you need to re-frame your mindset. Instead of porn addiction, start seeing yourself as a porn enthusiast. See yourself as a pleasure connoisseur. Stop thinking that there is something wrong with your fantasies, when really you just have a compulsive urge to make me happy.
