It may involve touching any part of the body, including the genital area. A person who practices frotteuristic acts is known as a ''frotteur''.<ref>{{cite book |last1=Sutton |first1=April G. |title=Encyclopedia of Sexual Psychology and Behavior |date=2023 |publisher=Springer, Cham |isbn=978-3-031-08956-5 |pages=1–2 |chapter-url=https://link.springer.com/referenceworkentry/10.1007/978-3-031-08956-5_1017-1 |language=en |chapter=Frotteurism |doi=10.1007/978-3-031-08956-5_1017-1}}</ref>
'''Toucherism''' is sexual arousal based on grabbing or rubbing one's hands against an unexpecting (and non-consenting) person. It usually involves touching breasts, buttocks or genital areas, often while quickly walking across the victim's path.<ref>Cantor, J. M., Blanchard, R., & Barbaree, H. E. (2009). Sexual disorders.

== Etymology and history == Frotteuristic acts were probably first interpreted as signs of a psychological disorder by French psychiatrist Valentin Magnan, who described three acts of "frottage" in an 1890 study. "Frottage" derives from the French verb ''frotter'', meaning "to rub". ''Frotteur'' is a French noun literally meaning "one who rubs". It was popularized by German sexologist Richard von Krafft-Ebing in his book ''Psychopathia Sexualis'', borrowing from Magnan's French terminology. Clifford Allen later coined ''frotteurism'' in his 1969 textbook of sexual disorders.<ref name="lussier" />
The ''Diagnostic and Statistical Manual of Mental Disorders'' called this sexual disorder by the name ''frottage'' until the third edition (DSM III-R), but changed to ''frotteurism'' in the fourth edition,<ref>{{cite book| edition=2nd | title=Sexual Deviance, Second Edition: Theory, Assessment, and Treatment | publisher=Guilford Press | url=https://books.google.com/books?id=g3TOLfeSlVkC&pg=PA133 | access-date=July 25, 2013 | last1=Laws | first1=D.

== Symptoms and classification == The professional handbook of the American Psychiatric Association (APA), the ''Diagnostic and Statistical Manual of Mental Disorders'', fifth edition, lists the following diagnostic criteria for ''frotteuristic disorder''.
* Over a period of at least 6 months, recurrent and intense sexual arousal from touching or rubbing against a nonconsenting person, as manifested by fantasies, urges, or behaviors. * The individual has acted on these sexual urges with a nonconsenting person, or the sexual urges or fantasies cause clinically significant distress or impairment in social, occupational, or other important areas of functioning.
If the individual has not acted on their interest and experiences no distress or impairment, they are considered to have a frotteuristic sexual interest, but not frotteuristic disorder.<ref name="DSM 5" /> Some sexologists distinguish between frotteurism (as pelvic rubbing) and toucherism (as groping with hands), but the DSM does not.<ref>{{cite book |author1=McAnulty, Richard D. |author2=Adams, Henry E. |author3= Dillon, Joel |name-list-style=amp |editor1=Sutker, Patricia B. |editor2=Adams, Henry E. | year = 2002 | chapter = Sexual disorders: The paraphilias | title = Comprehensive handbook of psychopathology | location = New York | publisher = Plenum Press | page = 761}}</ref> Sexologist Kurt Freund described frotteurism and toucherism as courtship disorders that occur at the tactile stage of human courtship.<ref>Freund, K.

== Etiology == There is no consensus as to the reason for why one would partake in frotteurism but there are many theories. Such theories include neurophysiologic abnormalities, mental disorders, psycho-social factors and sexual excitement.<ref>{{Cite book |last=Fallon |first=L.

Some comorbid mental disorders that can be associated with frotteurism are social anxiety, substance abuse, and a presence of other paraphilia symptoms.<ref name=":1">{{Cite journal |last=Guterman |first=Jeffrey T. |last2=Martin |first2=Clay V. |last3=Rudes |first3=James |date=March 2011 |title=A Solution-Focused Approach to Frotteurism |url=http://guilfordjournals.com/doi/10.1521/jsyt.2011.30.1.59 |journal=Journal of Systemic Therapies |language=en |volume=30 |issue=1 |pages=59–72 |doi=10.1521/jsyt.2011.30.1.59 |issn=1195-4396|url-access=subscription }}</ref> As for psycho-social factors, abnormal sexual stimuli growing up, sexual abuse, or poor parenting have been proposed as contributing factors.

== Diagnosis == In order to determine if someone is suffering from frotteuristic disorder, the individual goes through a set of clinical interviews and diagnostic criteria that are based on DSM-5. In some cases, laboratory workup and imaging are ordered to exclude other possible causes. Interviewing the individual is used to determine their history, such as any family history, sexual abuse, psychiatric disorders, chronic physical illness, or substance abuse. In younger individuals, a clinician may gather information about their academic performance, family dynamics, and any other home or developmental factors that may contribute to behavioral difficulties.<ref name=":2" /><ref>{{Cite journal |last=Bhatia |first=Manjeet Singh |last2=Jhanjee |first2=Anurag |last3=Srivastava |first3=Shruti |last4=Kumar |first4=Pankaj |date=October 2010 |title=An uncommon case of hypersexual behaviour with frotteurism |url=https://journals.sagepub.com/doi/10.1258/msl.2010.010103 |journal=Medicine, Science and the Law |language=en |volume=50 |issue=4 |pages=228–229 |doi=10.1258/msl.2010.010103 |issn=0025-8024|url-access=subscription }}</ref>
== Prevalence and legality == The prevalence of frotteurism is unknown. The DSM estimates that 10–14% of men seen in clinical settings for paraphilias or hypersexuality have frotteuristic disorder, indicating that the population prevalence is lower. However, frotteuristic acts, as opposed to frotteuristic disorder, may occur in up to 30% of men in the general population.<ref name="DSM 5" /> The majority of frotteurs are male and the majority of victims are female,<ref>{{Cite web |url=http://www.soc.ucsb.edu/sexinfo/article/frotteurism |title=UCSB's SexInfo<!-- Bot generated title --> |access-date=May 13, 2009 |archive-date=January 18, 2018 |archive-url=https://web.archive.org/web/20180118131704/http://www.soc.ucsb.edu/sexinfo/article/frotteurism |url-status=dead }}</ref> although female on male, female on female, and male on male frotteurs exist. This activity is often done in circumstances where the victim cannot easily respond, in a public place such as a crowded train or concert. Marco Vassi's story "Subway Dick" is an example of such acts in a train.<ref>''The Giant Book of Erotica''; ed. Colette Saint Germain. London: Magpie Books, 1993 {{ISBN|1-85487-183-8}}; pp. 469-77.</ref>
Usually, such nonconsensual sexual contact is viewed as a criminal offense: a form of sexual assault albeit often classified as a misdemeanor with minor legal penalties. Conviction may result in a sentence or psychiatric treatment.<ref>[https://web.archive.org/web/20091026134154/http://geocities.com/openlcc/se601.html frottophilia] at SEX ED 601 Advanced Topics in Human Sexuality.</ref>
