Prostitutes
Freud explains, “Prostitutes exploit the same polymorphous, that is, infantile, disposition for the purposes of their profession; and, considering the immense number of women who are prostitutes or who must be supposed to have an aptitude for prostitution without becoming engaged in it." Prostitutes could exhibit perversions because they deal with clients with divergent sexual behaviors. Their ability to engage and adapt to various sexual behaviors, some of which are perverse, demonstrates that sexual perversions are innately human attributes.
Children
Freud observes, “Small children are essentially without shame, and at some periods of their earliest years show an unmistakable satisfaction in exposing their bodies, with special emphasis on the sexual parts. " Here, the children's consciousness with their genitals confirms that the Sex instinct is not inactive or dormant during childhood. Observation of genitals offers them sexual feelings despite being children.
Jean Jacques Rousseau
Freud explains, “Ever since Jean Jacques Rousseau's Confessions, it has been well known to all educationalists that the painful stimulation of the skin of the buttocks is one of the erotogenic roots of the passive instinct of cruelty (masochism).” Rousseau’s theory implies that buttocks are an erotogenic region that could impact the libidos of children when it is subjected to corporal punishment.
Girls
Freud elucidates, “Little girls do not resort to denial of this kind when they see that boys' genitals are formed differently from their own. They are ready to recognize them immediately and are over-come by envy for the penis—an envy culminating in the wish, which is so important in its consequences, to be boys themselves." Freud implies that Girls envy boys due to the boys' penises ('penis envy'). As a result of envy, the girls feel that their clitorises are equivalent to the boys' penises.
Babies
Freud observes, “Many people can remember clearly what an intense interest they took during the prepubertal period in the question of where babies come from. The anatomical answers to the question were at the time very various: babies come out of the breast, or are cut out of the body, or the navel opens to let them through.” The questions concerning the origin of babies, which are dominant during childhood, allude to the consciousness that children have regarding sexuality.
