The father of psychoanalysis Sigmund Freud (1856-1939), in his book Three Essays for a Sex Theory, refers in various sections to fetishism as a perverse manifestation.
Some psychoanalysts consider fetishism as the perverse nucleus, or commonplace of all paraphilias.
The French psychoanalyst Guy Rosolato (1923-2012), in his book Essays on the Symbolic, considers that fetishism is in the first instance a manifestation of the problems that the subject has with the norm, which in other states can be manifested in sadomasochism, transvestism , voyeurism, among others.
The Italian psychoanalyst Piera Aulagnieur (1923-1990) considers fetishism as a border state of the subject, the last barrier before psychosis, in which there is a deep fixation by the object to stay within the limits of neurosis.
Other psychological theories about sexual fetishism relate it to theories of human behavior and the idea of ”conditioning” or learning.
Thus, some experience in childhood could cause the association between sexual pleasure and a certain object, a relationship that would remain in adulthood.
There are authors who do not consider the attraction to parts of the body as fetishism, but call this paraphilia “partialism.”
In fetishism, the fetish object can be used during masturbation or worn by the other member of the couple during sexual activity, for example, stockings, high-heeled boots, shoes, or a woman smoking (known as capnolagnia or capnogalia) in order to provoke the excitement of his sexual partner, since often the fetish is necessary for sexual arousal.
