The struggle of stuttering is caused from trying to control it. So it's kind of paradoxical to try to solve the struggle by trying to control the stutter even more. The way to get through stuttering is by allowing it. Therapy for this is called stuttering affirming therapy. I know plenty of people who stutter who are great conversationalists and charismatic. The idea that you would be a way more fun person is just part of having a stutter, it's usually not based in reality.
