NS (Golden Shower) or GS (Golden Shower) refers to the use of urine in sex work—as a fetish practice. A distinction is made between "NS active" (the sex worker urinates) and "NS passive" (the client urinates on the sex worker or vice versa). Typically only on the body, not on mucous membranes.
Low health risk if the skin is intact. Often a premium service for the sex worker; hydration before the appointment is necessary.
