Golden shower
A Golden Shower is an erotic act during which a participant urinates upon a partner, or partners. Primarily a kink behaviour rather than something routinely practiced by the majority of couples, it can be part of a humiliation scene or simply as an act of dominance. Golden Showers can be gay or straight, the partner providing the 'shower' male or female. Participants may be clothed or unclothed.
In some countries depiction of urine in porn has been declared illegal, in New Zealand for example: "the use of urine or excrement in association with degrading or dehumanising conduct or sexual conduct" is forbidden.
