Cottaging is a slang term which refers to men having sex in public toilets or cruising for sexual partners with the intention of having sex elsewhere. When same-sex relationships were still illegal, men who were gay or bisexual had very little options when it came to where they could have sex, so they would find discreet places where they wouldnt`t be caught such as a public toilet. The sex between the men would usually, but not always, be anonymous. Glory holes between the stalls became a way the men could remain faceless. Cottaging is illegal. You could be arrested under the Sexual Offences Act 2003 and charged with engaging in sexual activity in a public lavatory. This applies to both homosexual and heterosexual activity.
