In this book, Mathias Hirsch addresses the sexualized aggression of mothers towards their sons. He describes in detail the psychodynamics and the traumatic consequences of an incestuous closeness to the mother, which is facilitated by an absent or weak father. The son, bound by incest, must either exert power over his love object as an adult to fend off the panic of intimacy that arose from the original trauma, or he adopts a masochistic position and identifies with the victim role. Through his detailed and vivid case presentations, Hirsch shares his extensive clinical experience with readers and provides valuable insights on how to therapeutically approach such patients. In doing so, the author builds on his groundbreaking work.
