Psychosexual development
Phallic stage

Initially, Freud applied the theory of the Oedipus complex to the psychosexual development of boys, but later developed the female aspects of the theory as the feminine Oedipus attitude and the negative Oedipus complex. The feminine Oedipus complex has its roots in the little girl's discovery that she, along with her mother and all other women, lack the penis which her father and other men possess. Her love for her father then becomes both erotic and envious, as she yearns for a penis of her own. She comes to blame her mother for her perceived castration, and is struck by penis envy, the apparent counterpart to the boy's castration anxiety.
