- Sexual norms and behavior
o What is normal or desirable vary with time and place
§ 19th and early 20th centuries
· Excess sexual expression was problematic
§ Contemporary Western worldviews
· Inhibition of sexual expression is seen as a problem
o Sexual revolution of 1970s
§ Availability of birth control led to shifts in attitudes toward premarital sex
- Research methods in the study of sexuality
o Research focused on normative sexual behavior has gone through a series of revolutions
§ 1940s research focused on interviewing people about their sexuality
§ 1950s use of direct observations and physiological assessments during masturbation or sexual intercourse
o Physiological responses to sexual stimuli can be assessed using penile or vaginal plethysmographs
o Stigma may interfere with sexuality research
- Gender and sexuality
o Men are more likely to
§ Meet the diagnostic criteria for paraphilic disorder
§ Endorse engaging in masturbation and using pornography
o Women are more likely to report sexual dysfunction
o Gender differences in sexuality have decreased over time
o Reported gender differences in sexual behavior may reflect respondents’ attempts to match cultural expectations
o Older research in male samples concluded that sexual interest preceded subjective arousal and would be followed by biological arousal
o However, later research that included women found that sexual interest and subjective arousal often co-occur so sexual interest would often follow biological arousal for women
- DSM-5 disorders involving sexual interest, desire, and arousal

- Etiology of sexual dysfunctions
o Biological influences
§ DSM-5 includes separate diagnoses for sexual dysfunctions caused by medical illnesses
· Somewhat controversial because many sexual dysfunctions have a biological contribution
§ Biological influences include
· Diabetes, multiple sclerosis, spinal cord injury, heavy alcohol use before sex, chronic alcohol use, heavy cigarette smoking
§ Autonomic nervous system
· Excessive activation of SNS (inhibits blood flow to genitals)
· Deactivation of PNS
§ Hormone levels
· Low levels of testosterone or high levels of anabolic steroids or testosterone supplements
§ Side effect of some medications
· SSRIs can blunt sexual activity—serotonin increases inhibition of sexual responses

§ Behaviors are done with nonconsenting persons
o Divided categories based on source of arousal
§ Sexual attractions based on inanimate objects
§ Sexual attractions based on children
o Accurate prevalence statistics are not available
o Fantasizing or engaging in many of these behaviors may be relatively common and not necessarily part of a clinical disorder
o Fetishistic disorder
§ Reliance on an inanimate object or nongenital part of the body for sexual arousal

o Causes marked distress or impairment in functioning
o Etiology of paraphilic disorders
§ Neurobiological influences
· Almost all individuals with paraphilias are men
· They do not have unusual levels of testosterone or other androgens
§ Psychosocial influences
· History of childhood sexual abuse: 40-66% of adult sexual offenders reported a history of sexual abuse
· Loss of control over behavior
· Heightened impulsivity and poor emotion regulation
· Poor recognition of emotional expression of others
· Slightly lower IQ and higher rates of neurocognitive problems
· More minor physical anomalies related to prenatal development
o Treatment for the paraphilic disorders
§ Very little is known about the effectiveness of treatments
· Research often focuses on men charged with sexual offense
· Very little long-term data is available
· Unethical to withhold treatment
o Lack of control groups (RCTs)
§ Treatments aim to enhance motivation for treatment
· Bolster hope for control over urges
· Focus on benefits for change and consequences of continued engagement in illegal sexual behaviors
§ Cognitive behavioral
· Aversion therapy
o Pair paraphilic fantasies with aversive stimuli
· Covert sensitization
o Asked to imagine negative consequences of inappropriate sexual behavior
· Modify distorted thinking
· Often combined with social skills, sexual impulse control strategies, empathy training, and relapse prevention
§ Biological
· Medications (supplement to psychological treatment)
o Hormonal agents to reduce androgens
§ Limited RCT data available and difficult to interpret due to drop out rates
§ Lack of evidence of elevated androgens in paraphilic disorders, which suggests androgens may not be a good treatment target
o SSRIs
§ Used despite lack of empirical support
o Prevention
§ Often treatment only takes place after an individual is charged with a crime
§ In 2004, major efforts began to try to identify and intervene with men who experience sexual attractions to children through community outreach across several countries
§ Cognitive behavioral therapy and medication approaches
§ Some evidence of effectiveness of these approaches
o Balancing public protection vs. civil liberties of offenders
§ Balance between protecting the public and protecting the civil liberties of sexual offenders
· E.g., laws concerning the public’s “right to know” when a sex offender is released
§ Unconstitutional to detain a person based on potential for future crimes. However:
· Supreme court ruled that a person at high risk for a sex crime can be detained if the risk is related to a psychological disorder diminishing the person’s ability to control sexual behavior
§ Receipt of a paraphilic diagnosis can lead to placement in a psychiatric facility after a prison term is completed
