Sexual Desire Disorders Hypoactive sexual desire disorder Deficient or absent sexual fantasies and urges Low sex drive Cultural norms influence perceptions of how much sex a person should want Sexual aversion disorder Individual actively avoids nearly all genital contact with another person

Gender Identity Disorder
Formerly known as transsexualism Individuals feel that they are of the opposite sex Despite normal genitals Feelings usually present since childhood May seek out surgery to alter body Feelings must cause distress or impairment or no diagnosis is given Individuals with GID may be sexually attracted to same or opposite sex individuals Prevalence: 1 in 12,000 in men 1 in 30,000 in women
19
Gender Identity Disorder
Controversial diagnostic category Should it be a psychiatric disorder? Diagnosis pathologizes a natural diversity found in nature Also carries stigma GID can be diagnosed in children Cross-gender behaviors common in kids Most children with GID grow up to be comfortable with their biological sex without professional intervention
20
Etiology of Gender Disorder
Genetic factors symptoms of gender identity during childhood are at least moderately heritable Neurobiological factors Exposure to high levels of sex hormones in utero Social and psychological factors Reinforcement of cross gender behaviors
21
Treatment of Gender Identity Disorder
Sex reassignment surgery Genitalia altered to look like those of opposite sex 1 year living as opposite sex before surgery recommended Behavioral treatment to alter gender identity Shaping of more masculine behaviors May only be effective for individuals who want treatment for GID

Table 13.4 Paraphilias included in DSM-IV-TR
23
Fetishism Reliance on an inanimate object for sexual arousal
e.g., shoes, stockings, underwear, rubber garments Occurs most often in men Object often necessary for sexual arousal Attraction to object irresistible and involuntary Fetishes often co-occur with other paraphilias
24
Transvestic Fetishism
Transvestic Fetishism orTransvestism Recurrent and intense sexual arousal from cross-dressing No desire to be of the opposite sex Always men, many of whom are married and conventional in other ways Often comorbid with other paraphilias Especially masochism

26
Incest Subtype of pedophilia Most common
Brother and sister Less common but more pathological Father and daughter Incest taboo almost culturally universal Genetically adaptive Offspring of father-daughter or brother-sister have a greater likelihood of inheriting pairs of recessive genes with possible negative biological effects.
27
Voyeurism Voyeuristic fantasies are common
Sexually arousing fantasies, urges, or behaviors while observing other who are unclothed or engaging in sexual activity Almost always men Excitement comes from knowing the victim is unaware of the voyeur Seldom results in physical contact Orgasm achieved by masturbation Victims unaware that they are being watched Voyeuristic fantasies are common Fantasies that are not distressing do not warrant diagnosis
