Query: Not the Cal I Knew

I met Cal before he became a porn star, and I remained an acquaintance until his death. Yes, I shared some sexcapafes with him in the early years; but mainly he was an occasional friend who came to dinner every so often. He was an able,intelligent,educated man who never achieved his goal of being a legitimate theatre star. For example, I had no hesitation about using him as an invited guest speaker at some of my university courses. I was also always a little saddened about how he let people use him. I know he tried to create an aura for the public but I would have expected a perceptive author to uncover more of the real man. This simply is not the Cal I knew.
