Urolagnia
Urolagnia (also known as urophilia) is a paraphilia involving sexual attraction to urine.
People with urolagnia often like to urinate in public, or urinate on, or be urinated on by, other people, and may drink the urine. Some like to watch others doing these things. These activities are often described by the euphemisms "golden showers" or "watersports" (which should not be confused with water sports).
In contrast to practices such as coprophagia, it is generally considered harmless, as the urine of healthy individuals is sterile. However, a small risk exists if there is disease present, or bacterial infection of the urethra. There may also be secondary effects, such as skin rashes in individuals sensitive to urine.
In the absence of STDs, urine is generally safe to consume in small quantities. The main dangers are the high salt and mineral content and acidity. After drinking urine or placing it in the mouth, one should rinse one's mouth and brush one's teeth in order to mitigate the effects of the acid on the teeth. The high salt content usually does not pose a problem if the urine is sufficiently diluted and not consumed in mass quantities. One may also wish to drink some water after consuming urine in order to mitigate the effect of the high salt and acidity. The person whose urine will be consumed may also wish to drink some water (or diet soda, see below) several hours before the act in order to dilute the urine.
Since artificial sweeteners are excreted in urine, consuming artificial sweetener before urine play can lend a sweet taste to the urine. Drinking diet soda, or other beverages containing artifical sweetener, before urine play will have the dual effect of diluting the urine and sweetening it. However, if you taste sugar in you or your partner's urine and you or your partner have not consumed artificial sweetener, this may be a sign of diabetes and you should see a doctor.
It is safer to drink the urine of men than of women, because the relative proximity of the urethra to the anus in the female body means that female urine is more likely to contain traces of feces.
Urolagnia is sometimes associated with, or confused with, a sexual attraction to someone experiencing the discomfort or pain of a full bladder, a sadomasochistic inclination.
Other mammals
Male porcupines use urine to soften the females' quills before mating.
Male elephants urinate on themselves, and roll in urine-filled mud as a method of attracting females.
