Phallic stage

In the phallic stage of psychosexual development, a boy's decisive experience is the Oedipus complex describing his son–father competition for sexual possession of his mother.

This psychological complex indirectly derives its name from the Greek mythologic character Oedipus, who unwittingly killed his father and sexually possessed his mother.

Moreover, after the phallic stage, the girl's psychosexual development includes transferring her primary erogenous zone from the infantile clitoris to the adult vagina.

Freud thus considered a girl's Oedipal conflict to be more emotionally intense than that of a boy, resulting, potentially, in a woman of submissive, less confident personality.

[6] An unresolved fixation in the phallic stage could lead to egoism, low self esteem, flirtatious and promiscuous females, shyness, worthlessness and men that treat women with contempt.
