Cottaging is a British gay slang term referring to anonymous sex between men in a public lavatory (a "cottage", "tea-room" or "beat"), or cruising for sexual partners with the intention of having sex elsewhere. The term has its roots in self-contained English toilet blocks resembling small cottages in their appearance; in the English cant language of Polari this became a double entendre by gay men referring to sexual encounters.
"Cottage" is documented as having been in use during the Victorian era to refer to a public toilet and by the 1960s had become an exclusively homosexual slang term. The word used in this sense is predominantly British (a cottage more commonly being a small, cosy, countryside home), though the term is occasionally used with the same meaning in other parts of the world. Among gay men in America, lavatories used for this purpose are called tea rooms.
Cottages were and are located in places heavily used by many people such as bus stations, railway stations, airports and university campuses. Often glory holes are drilled in the walls between cubicles in popular cottages. Foot signals are used to signify that one wishes to connect with the person in the next cubicle. In some heavily used cottages, an etiquette develops and one person may function as a lookout to warn if non-cottagers are coming.
Since the 1980s, more individuals in authority have become more aware of the existence of cottages in places under their jurisdiction and have reduced the height of or even removed doors from the cubicles of popular cottages, or extended the walls between the cubicles to the floor to prevent foot signalling.
Cottages as meeting places
The Internet is transforming cottaging from an activity engaged in by men with other men, often in silence, and who do not communicate beyond the markings of a cubicle wall. Today an online community is being established in which men exchange details of locations, discussing aspects such as when it receives the highest traffic, when it is safest and to facilitate sexual encounters by arranging meeting times. The term cybercottage is used by some gay and bisexual men who use the role-play and nostalgia of cottaging in a virtual space or as a notice board to arrange real life anonymous sexual encounters.
Historically in the United Kingdom, public gay sex often resulted in a charge and conviction of gross indecency, an offence only pertaining to acts committed by males and particularly applied to homosexual activity. The Sexual Offences Act 1967 permitted homosexual sex between consenting adults over 21 years of age when conducted in private. The act specifically excluded public lavatories from being "private". The Sexual Offences Act 2003 eventually removed this contentious offence in favour of "indecent exposure".
In many of the cases where people are brought to court for cottaging, the issue of entrapment arises. Since the offences are public but often carried out behind closed doors, the police have found it easier to use undercover police officers who would frequent toilets posing as homosexuals in an effort to entice other men to approach them for sex. These men would then be arrested for indecent assault. Such practices were severely curtailed after a judge decided the police officer in the case had consented to the assault if he had desired and required the defendant to touch him with sexual intent in order to have evidence of a crime. Alternatively, they were arrested for importuning, with a much lower burden of proof, shorter maximum sentence, yet equal potential devastation of life, which was, arguably, the "aim of the game" for police at the time.
Timeline of historic cases
|1943||Newspaper editor Clarence McNulty was arrested for wilfully and obscenely exposing his person in the Lang Park toilets near Wynyard train station in Sydney, Australia. He denied the charges and this early case highlighted the practice of the police using pretty policemen (i.e. as "bait") to entrap the public. As only one police officer was present in the toilet, the magistrate determined that the police were unable to correctly corroborate the evidence and gave McNulty the benefit of the doubt.|
|1946||Sir George Robert Mowbray, 5th Baronet Mowbray, was fined for importuning men at Piccadilly Circus Underground station.|
|1940s||Tom Driberg charged with indecent assault after two men shared his bed in the 1940s and used his position as a journalist several times to get off later charges when caught soliciting in public toilets by the police.|
|1953||Actor Sir John Gielgud was arrested and fined £10 for cottaging ("persistently importuning").|
|1953||MP William J. Field was arrested for persistently importuning in a public toilet. Field appealed against the conviction twice but failed on both occasions.|

|1962||On 6 November 1962, actor Wilfrid Brambell was arrested in a toilet in Shepherd's Bush for persistently importuning.|
|1962||In 1962, the Mansfield Police Department conducted a sting operation in which they covertly filmed men having sex in the public restroom underneath Central Park. Thirty eight men were convicted and jailed for sodomy. After the arrest, the city closed the restrooms and filled them in with dirt. The police later made a training film of the footage. It was rereleased in 2007 as "Tearoom".|
|1964||In October, President Lyndon B. Johnson's aide Walter Jenkins was arrested in a YMCA in Washington, D.C., and the case was subsequently dismissed.|
|1968||Michael Turnbull was arrested in Hull for cottaging in a public toilet, before he became Bishop of Durham.|
|1975||In September 1975, actor Peter Wyngarde was arrested (under his real name, Cyril Louis Goldbert) in Gloucester bus station public toilets for gross indecency with Richard Jack Whalley (a truck driver). He was fined £75.|
|1976||Sixty-six-year-old retired U.S. Major General Edwin Walker made sexual advances to an undercover police officer in a restroom at a park in Dallas, Texas on June 23, 1976, and was arrested for public lewdness. The general pleaded no contest and was fined $1,000 and court costs.|
|1976||Former Judge G. Harrold Carswell was convicted of battery for advances he made to an undercover police officer in a Tallahassee men's room.|
|1981||Coronation Street actor Peter Dudley was observed exposing himself to another man in a public toilet in Didsbury, Manchester, and was charged with importuning. He pleaded guilty and was fined £200. Some months later, Dudley was charged again with gross indecency for an alleged similar offence, though this time he claimed he was not guilty and had been set up by the police. A Crown Court jury failed to reach a verdict, but while waiting for a retrial, Dudley suffered a series of strokes and heart attacks and died in October 1983.|
|1984||Actor Leonard Sachs was fined for importuning in a public toilet.|
|1988||Australian radio personality Alan Jones was arrested in a public lavatory block in London's West End and charged with two counts of outraging public decency by behaving in an indecent manner under the Westminster by-laws. He was later cleared of all charges and awarded costs.|
|1990||British pop star Stedman Pearson (of the group Five Star) appeared at Kingston Magistrates Court in October 1990 and pleaded guilty to a charge of public indecency after being arrested in a public toilet in New Malden in London.|
|1998||In April 1998, pop star George Michael was arrested for "engaging in a lewd act" in a public toilet in Los Angeles after a sting operation by local police. Although he considered the arrest to be police entrapment, he pleaded "no contest" to the charge in court and was fined $810 and ordered to do 80 hours of community service. Later that year, Michael satirised the events in his music video for the song "Outside" and was sued by one of the officers in the original arrest for portraying him as non-heterosexual and mocking him. The suit was ultimately dismissed.|
|1998||In October 1998, UK Labour Party MP Ron Davies was mugged at knife point on Clapham Common. He resigned after it became clear he was engaging in homosexual activities in a known cottaging area.|
|2007||US Senator Larry Craig was arrested in the men's public toilet in the Lindbergh Terminal of the Minneapolis-Saint Paul International Airport in Minneapolis, Minnesota, for allegedly soliciting sex. Craig later pleaded guilty to disorderly conduct and announced his intent to resign from office, which he later rescinded. He has since contested his guilty plea and has repeatedly tried to bring the matter to trial.|

Evidence of sexual activity in these spaces has traditionally taken the form of sexualised graffiti and/or the drilling of holes in lavatory holes. These holes are termed "glory holes" and dependant upon their size may be to pass a penis through in order for the men to engage in anonymous oral sex and on rare occasions intercourse. They more often serve as a peep hole through to the other toilet or out towards the urinals. On those occasions the person entering the cubicle would check that the adjacent cubicle is empty before unblocking the cubicle hole. These holes are often blocked up by tissue paper which will be removed so that one cubicle occupant can view through to the other. The addition of metal plating on cubicle walls is often an effective mechanism of preventing this. Alternatively the cubicle can be designed with a solid brick wall so as to make the cutting or drilling of a hole impossible."

But it then becomes compulsive and a mechanism for avoiding sorting your life out" ... This month sees the publication of a survey of men who cottage in north London by the Aids Education Unit of Barnet Healthcare NHS Trust. More than 200 men were asked to complete an anonymous questionnaire, and the results are eye-opening. Twenty per cent of those questioned started cottaging between the ages of 10 and 14, and 32 per cent started between the ages of 15 and 19. And the survey's finding that just over 75 per cent of those questioned also regularly visit gay social venues and groups somewhat destroys the myth that cottagers are sad, closeted individuals who are unable to come to terms with their sexuality."

"Just as the creation of the information society has allowed for the expansion in e-commerce and online communication, so too has it allowed for the expansion of online sites and communities that support minority sexual practices and activities. One such activity is the cottaging phenomenon, which involves men seeking sexual satisfaction in public lavatories with other men. Like many other groups, participants in this online community have embraced the emerging technology, utilising message boards and online discussion to offer advice, spread awareness of locations, arrange sexual meetings in the physical world and share cautions and warnings."
