The genital stage is the fifth stage of psychosexual development that begins with the onset of puberty and continues to adulthood - 13 years to death. At this time, individuals start to become sexually mature and begin to explore their sexual feelings and desires more maturely and responsibly.
According to Freud, this is when an individual begins to have a strong sexual interest in the opposite sex. And, if the stage is successful, this is when folks develop loving and search for life-long relationships with someone of the opposite sex.
In classical psychoanalytic theory, the final stage of psychosexual development commenced in puberty when the Oedipus complex has been fully resolved and erotic interest and activity are focused on bodily contact with a sexual partner.
A. Genital Stage task - The genital stage commences when all the libidinal urges and aggressive drives made a grand comeback. If you remember in the phallic stage, (the Oedipal and Elektra complex) the challenge for the child is centered on their resolution. On the other hand, the source of sexual pleasure in the genital stage has broadened and widened and has stepped outside of the family triangle (mother and father). The individual has now expanded his/her horizon and saw sexual and love interests outside of their home.
At age 3-6, if the child unknowingly grows fondness and becomes attracted to the same-sex parent ... then homosexual relationships are highly probable. However, the slant and the direction of this viewpoint and how we understood the phallic stage, become contradictory and incompatible with what we primarily believed the phallic stage entails.
