Which theory is the most sexual and the most sexist? That would be the psychodynamic theory. However, psycho-dynamic theory is basically the study of human behavior that includes internal processes, personality, motivation, drives, and the importance of childhood development (Tavris & Wade, 1998). The psycho-dynamic theory, developed by Sigmund Freud, emphasizes the interplay of unconscious psychological processes in determining human thought, feelings, and behavior. The basis of this approach is that psychological factors play a major role in determining behavior and shaping personality. Freud divided the human psyche into three; the id, ego and superego. He said you were born with id which was in your unconscious and it comprised of selfishness and lack of awareness. The other two parts; the ego and superego were said to be in your conscious. The ego was comprised of awareness and consciousness and the superego of definite conscious where you begin caring about others (IoHT). The psycho-dynamic theory believes our actions are a result of the inner struggle between the id, ego, and superego. The psychodynamic theory suggests that the id may cause aggression and would be considered bad.

             The main aspect of the psycho-dynamic theory is that behavior is directed by forces within one's personality, but is usually hidden in the subconscious. According to Freud, behavior is caused by unconscious thoughts, impulses and desires. He also theorized that many of our unconscious thoughts are too hard for us to deal with and so we repress them. Freud believed that personality develops in psycho-sexual stages; in each stage a part of the body becomes the child's main source of pleasure (Mcleod). Failure to resolve conflicts at any stage can cause fixation, an unconscious preoccupation with the pleasure area associated with that stage. The five stages that an individual goes through during life are the oral stage, the anal stage, the phallic stage, the latency stage, and the genital stage.
