Golden showers, water sports, or piss play: No matter what you call it, it’s considered relatively safe. Pissing on unbroken skin carries no risk for transmission of HIV. Drinking piss has almost little or no HIV risk. If someone has some other STD, drinking piss carries a risk of transmission, but low. If you are into drinking your partner’s piss, keep in mind that piss is one of your body’s ways of getting rid of excess or unwanted substances such as vitamins, crystal meth, recreational drugs, medications and even hormones. Know the pisser, know the risk.
Shit can contain blood, so it can transmit infections such as HIV and hepatitis. Shit can also transmit parasites and harmful bacteria. If you have a cold or canker sore or have recently brushed your teeth vigorously or flossed, and get shit in your mouth, you can be at risk for STDs, HIV or other infections.
With enemas, don’t share your douche/enema bag. Clean it and the nozzle after every use. It’s recommended not to share metal shower nozzles, but if you do, cleaning it with a hospital grade disinfectant solution or soaking in a 10% chlorine bleach solution will minimize your risk. Make sure though that after sterilizing it you rinse it really well with hot water before putting it up your ass. And don’t douche or have an enema after sex because you could be pushing bacteria or STDs further up into your body.
