Just FYI for those into or interested in trying piss play/watersports, who I see are oft quoting the misleading but very well known line about piss being completely sterile, it is not always completely true:
We’ve been taught since childhood that piss is dirty and we’d better wash our hands after we piss. People feel that watersports is edge play because it seems to be unhygienic, yet of all exchanges of body fluids, watersports is the least risky as the urine of a healthy person leaves the bladder nearly sterile. The acidic content is hostile to many bacteria and viruses. As many know, in the absence of pure water in World War II battlefields, urine was recommended as a substitute for cleaning wounds.

There is little to no chance of contracting HIV during piss play. The HIV virus is fragile and breaks down in the acidic liquid. The Centers for Disease Control has stated that urine doesn’t contain enough HIV to infect another person. However, watch out for a partner with an STD or a bacterial infection of the urethra. Hepatitis and other STDs may be passed along, although the risks of that are generally less than blood-to-blood contact or intercourse, but the risk is greatly increased in the presence of open cuts or bleeding gums.

Medications, other drugs, alcohol and vitamins may pass into the piss, and can be transferred if imbibed.

General good advice (as with all sexual partners) is to know the relevant condition/s of your partner before partaking.

Urine
is not acidic unless you have problems. If your urine is acidic enough to be antibacterial its sure gonna burn when you're taking a piss!

There was a bar in Amsterdam that stunk of piss and had a bath in the middle of the floor. I felt very uncomfortable but somehow extremely turned on by the fact that someone could be this....dirty....take me and make me wet now :)
