I found this book to be a good analysis of the historical aspects of castration of boys and men. There is also a great deal of psychoanalytic literature regarding the Castration Complex, and the sexualised desire of me to avoid Castration Anxiety through actual physical castration. These issues are also tied into the concept of the Phallic Mother, Incredibly complex really. I guess the ability to work out one's issues, and search for answers is going to be a salient feature of having offspring moving forward.
