which they do. There are two
             classifications for this they are: the libido, this is based on sexual pleasures, and the
             second type is called aggression this motivates the behavior. This type of thinking
             happens from the time a person is born, according to Freud. When growing up, the child
             will go though three different libidinal stages. The first is called the oral stage, in this
             stage the infant takes his or her thumb and stimulates the mouth with it, we may know
             this act as the baby sucking his or her thumb. The second stage of libidinal is the anal
             stage. In this stage, pleasures like the ones in the oral stage are similar. These pleasures
             are repeated through pleasures to the anus. The bowel movements mark this pleasure.
             The final stage in the libidinal stages of a child is the phallic stage. This is done when the
             child manipulates their genitalia in order for gratification. (Grolier)
