Frotteurism is a disorder in which a person derives sexual pleasure or gratification from rubbing, especially the genitals, against another person, usually in a crowd. The person being rubbed is a victim. Frotteurism is a paraphilia, a disorder that is characterized by recurrent intense sexual urges and sexually arousing fantasies generally involving objects, the suffering or humiliation of oneself or one's partner (not merely simulated), or children or other nonconsenting persons.
There is no scientific consensus concerning the cause of frotteurism. Most experts attribute the behavior to an initially random or accidental touching of another's genitals that the person finds sexually exciting. Successive repetitions of the act tend to reinforce and perpetuate the behavior.
In order for the disorder to be clinically diagnosed, the symptoms must meet the diagnostic criteria as listed in the professional's handbook, the Diagnostic and Statistical Manual of Mental Disorders. These symptoms include:
►Recurrent, intense, or sexually arousing fantasies, sexual urges, or behaviors that involve touching and rubbing against a nonconsenting person.
►The person has acted on these sexual urges, or the fantasies or urges cause significant distress to the individual or are disruptive to his everyday functioning.
Most people with frotteurism never seek professional help, but people with the disorder may come into the mental health system as a result of a court order. The diagnosis is established in an interview between the person accused of frotteurism and the mental health professional (a psychiatrist or a psychologist , for example). In the interview, the individual acknowledges that touching others is a preferred or exclusive means of sexual gratification. Because this acknowledgment can bring criminal charges, the disorder is underdiagnosed and its prevalence is largely unknown. In some cases, other people besides the accused may be interviewed, including observers or the victim.
For treatment to be successful, the frotteur must want to modify existing patterns of behavior. This initial step is difficult for most people with this disorder to take.Behavior therapy is commonly used to try to treat frotteurism. The frotteur must learn to control the impulse to touch nonconsenting victims. Medroxyprogesterone, a female hormone, is sometimes prescribed to decrease sexual desire.Frotteurism is a criminal act in many jurisdictions. It is usually classified as a misdemeanor. As a result, legal penalties are often minor. It is also not easy to prosecute frotteurs as intent to touch is difficult to prove. In their defense statements, the accused often claim that the contact was accidental.
