Sexual Disorders
Historical Perspective
• St-Augustine declared that sexual intercourse
was only allowed for procreation, only when the
man was on top, and only when the penis and
vagina were involved
• Many believed that masturbation caused a
variety of illnesses (see Tissot, 1758)
– Onania, or the Heinous Sin of Self-Pollution, And All
Its Frightful Consequences, in Both Sexes,
Considered was published in 19 editions and sold
38,000 copies before 1750

involving 1) nonhuman objects, 2) the
suffering or humiliation of oneself or one’s

is social dysfunction as a result of the
reaction of others to their behaviour”

Theories of fetish behaviour

between fetish object and sexual arousal
Cognitive theory = cognitive distortion and perceiving an
unconventional stimulus as sexual
Monoamine hypothesis = problems in monoamine
(serotonin, norepinephrine, dopamine) metabolism
Chapter 16

Theories of fetish (cont.)
Imprinting hypothesis = adolescents are
vulnerable to imprinting of various stimuli;
thus, experiencing a stimulus at a critical
period can lead to imprinting
Addiction theory =
when a behaviour has salience
modifies mood
Tolerance
Withdrawal symptoms
Conflict
relapse

Causes of Paraphilias
Theory
Description
Psychodynamic
theory
Fixation at early psychosexual stage or
regression to that stage.
Behavioral
Arousal is classical conditioned to a
previous neutral stimulus.
Social learning
Children whose parents engage in
aggressive, sexual behaviors with them
learned to engage in impulsive, aggressive,
sexualized acts toward others.
Cognitive
Distorted cognitions and assumptions about
sexuality lead to deviant sexual behavior.
Chapter 16
Copyright © 2004 by The McGraw-Hill Companies, Inc. All rights reserved.
Treatments: Cognitive Behavioural
Satiation  teach the individual to satiate
himself with the stimulus until arousal
decreases
Covert sensitization  associate negative
consequences to the precursors of his
atypical behaviour
Chapter 16
Copyright © 2004 by The McGraw-Hill Companies, Inc. All rights reserved.
Treatments: Cognitive Behavioural
Fading  shift fantasies from atypical to
acceptable
Cognitive restructuring  challenge
cognitive distortions that justify to the
patient his atypical behaviour
Chapter 16
Copyright © 2004 by The McGraw-Hill Companies, Inc. All rights reserved.
Treatments: Cognitive Behavioural
Victim empathy therapy  help patients
understand impact of their behaviour
Aversive stimulation  pair noxious
stimulus with the deviant fantasy in
order to interrupt the fantasy and
suppress the behaviour
Chapter 16
Copyright © 2004 by The McGraw-Hill Companies, Inc. All rights reserved.
Treatments: Relapse Prevention
Help individual identify factors that trigger
a relapse
E.g., high risk situations, behavioural chains
that lead up to the problem behaviour,
strategies to avoid these factors

DSM-IV Criteria for Gender Identity
Disorder, continued
B. Persistent discomfort with his or her sex and
a sense of inappropriateness in the gender
role of that sex.

Treatment of Gender Identity
Disorder
Therapists do not try to “cure” people with
gender identity disorder by convincing them
to accept the body with which they were born.
Gender reassignment requires several
surgeries and hormone treatments and is
primarily cosmetic. It remains a controversial
practice.
