Golden shower (watersports, GS/WS)
Play involving urine carries no risk of transmitting HIV or other infections as long as it consists of urinating on healthy skin. Try to avoid getting urine in your eyes, or on cuts or lesions.
Drinking urine carries a very low HIV risk. It’s only risky if the urine contains blood. On the other hand, some bacterial infections, like chlamydia or gonorrhea, can be transmitted by getting urine in the mouth or eyes.
Brown shower (scat, chocolate shower)
Contact with fecal matter doesn’t carry any risk of transmitting HIV as long as there is no blood, and the contact is with healthy skin. However, this practice can involve significant risk of bacterial infection, as well as the transmission of hepatitis A and B, and parasites.
