I read the beginning of a book many years ago and would like to figure out what book it was and finish it. The book was written before 1983, possibly many years before that. I read it no later than that. It was about a robot that had been built by a guy that gave it free will. When he activated the robot, it walked out and began exploring the world. It had a sort of face but it was described as being representative of an abstract face, not a copy of a human face. The robot liked this. Where a human would have genitals, the robot had a squarish box. At one point, there was a kind of vaguely erotic scene where the robot was being bathed by 3 girls. But, the robot was not a sexual creature and was not aroused or anything. He was more or less observing coldly. At least to the point that I got in the book, the robot seemed to be emotionless and detached. That's about all I remember.
