Alfred Kinsey was a very strange man. He was repressed sexually until quite a late age, and then expressed his sexuality in more and more bizarre forms as he grew older. His was a classic case of the appetite increasing with the feeding. Once you are on the treadmill of exploring sensation as the key to contentment, you have to experience more and more extreme things. I think this explains the logic of artistic production and how 'transgressive' becomes a term of praise.
