Some examples of complexes include the Oedipus complex, the Electra complex, the castration complex, and the inferiority complex. The Oedipus complex is the desire of a young boy to have sexual relations with his mother and kill his father. The Electra complex is the desire of a young girl to have sexual relations with her father and kill her mother. The castration complex is the fear of having one's penis cut off.
