Urolagnia (also urophilia, undinism, golden shower and watersports) is a paraphilia in which sexual excitement is associated with the sight or thought of urine or urination. The term has origins in the Greek Language (from ouron, urine, and lagneia, lust).[dead link]
As a paraphilia, urine may be consumed or the person may bathe in it. Other variations include arousal from wetting or seeing someone else urinate in their pants or underclothes, or wetting the bed. Other forms of urolagnia may involve a tendency to be sexually aroused by smelling urine-soaked clothing or body parts. In many cases, a strong correlation or conditioning arises between urine smell or sight and the sexual act. For some individuals the phenomenon may include a diaper fetish and/or arousal from infantilism.
Watersports may also be used in a BDSM scene as a form of humiliation, sometimes involving desperation until incontinence or infantilization, sometimes physical humiliation associated with being urinated on or pressured to consume urine. In some cases, a person is aroused by merely staging situations where others can either witness that person wet his or her clothing or smell his or her urine scent.
Urolagnia is sometimes associated with, or confused with, arousal from having a full bladder or a sexual attraction to someone else experiencing the discomfort or pain of a full bladder, possibly a sadomasochistic inclination. In the hanky code, urolagnia is symbolized by a yellow bandana in the right or left pants pocket.
Common variations 
- Omorashi – The act of holding one's own urine until the need to urinate is urgent, making another hold in their urine, or watching another person with an urgent need to urinate. This fetish sometimes originates from childhood memories of being or of seeing another needing to urinate. Arousal may be triggered by seeing the body movements or facial expressions of that person. It can also be heightened by the person saying that they have to urinate. The arousal from being desperate comes from the sensation of having a full bladder.
- Voyeurism – Seeing another urinate without the person's knowledge either through video taping by a hidden camera, or by lurking in locations where people are urinating or are likely to have an urge to urinate.
- Clothes wetting – The person is sexually aroused by wetting one's clothing or observing another person doing so. Usually that person prefers to stage the wetting so that his/her legs (or other body parts) become soaked with urine. The warm sensation felt when urine trickles on the body seems to give very relaxing and pleasurable feelings to the person. In many cases, that person is also aroused by smelling body parts that have a urine scent. Others get aroused by telling some people about when they lost control and wet themselves. Some prefer a particular type of clothing to urinate.
- Exhibitionism – Becoming noticeably desperate or wetting oneself with the express purpose of being seen by strangers. Practitioners have described going to public places such as a mall or a park. Some intend to create situations where others can see their wet clothing.
- Pussing – British expression for an activity involving a consenting couple where the male partner watches the woman urinate otherwise undetected in a semi-public place, usually a toilet cubicle at a pub, hotel, restaurant, theatre/cinema, office, club etc. The strategies and tactics that are used to smuggle one of the couple into and out of the toilet undetected are as important or almost as important as the urination. The activity is done by itself or as a part of or prelude to other activities which many times involve sex.
- Human Urinal - An act common in the bondage sex community where a male or female slave will serve as a urinal for a dominant man. The slave is usually strictly forbidden from placing their lips directly on the body of the dominant so the practice routinely involves them receiving much of the spray all over their face, hair and body.
Notable urophiliacs 
- Havelock Ellis – British sexologist who was impotent until at age sixty he discovered that he was aroused by the sight of a woman urinating.
- Annie Sprinkle – an American porn actress, later turned sex educator and advocate for female sexual enjoyment. Her stage name is derived from her obsession with fluids.
- Rockbitch – mostly female British band featuring many sexual acts including urination as part of their stage act.
- Ashley MacIsaac – Nova Scotian fiddler and singer. In 1996 he spoke with a Maclean's interviewer mentioning his sexual life, including his underage boyfriend and his taste for urolagnia. In 2003 he told an interviewer for the Montreal Mirror that he loves to have men urinate on him.
- Albert Fish – an American serial killer, also known as The Grayman, The Boogeyman. He wrote several letters to widows with want-ads in The New York Times and described in detail women urinating on him, inside of him, and in cups so that he could drink it. He later forced children to drink urine.
- Troughman – an Australian noted in the Sydney media for lying down in urinal troughs at Sydney Mardi Gras parties and other events.

"Female kob perform oral sex on each other and even stroke each other's vulvas with their forelegs. They may exhibit urolagnia during sex, one female will urinate while the other sticks her nose in the stream."
A male Patagonian mara, a type of rodent, will stand on his hind legs and urinate on a female’s rump, to which the female will respond by spraying a jet of urine backwards into the face of the male. The male’s urination is meant to repel other males from his partner while the female’s urination is a rejection of any approaching male when she is not receptive. Both anal digging and urination are more frequent during the breeding season and are more commonly done by males.
