Intro

For most men and women the term "water sports" implies some sort of sexual activity involving urine or urinating. There are clubs, societies and conventions especially for water sports afficionados.

Physiology

Urine is comprised of harmful wastes filtered out of your blood by your kidneys. Though it is most often sterile, it can contain bacteria (if you have a urinary tract infection or urethritis) and/or HIV. If you are diabetic, your urine will contain extra sugar. Other wastes frequently found in urine include nitrogen, potassium and sodium.

Technique

A partner urinates onto you, into you or you can drink his/her urine. Most likely there are many other permutations.

Complications

You may catch an infection if your partner's infected urine enters your body. A golden shower (urinating onto your body) is usually safe as long as it doesn't get into your eyes, nose, mouth or other orifices. Drinking urine or having a partner urinate into your anus or vagina will allow infections to pass into your body. If you drink your own urine you can transfer infections from your kidneys, bladder, or urethra to your mouth or throat.

Urine can contain caustic compounds that irritate your colon lining. You can develop a mild colitis (inflammation) which theoretically can make it easier to catch or transmit HIV. You will also absorb any chemicals in your partner's urine through your colon wall.

If you're not healthy, urine can contain substances that your body can't easily process. You will absorb whatever is in your partner's urine. If you have kidney problems, high blood pressure, diabetes or another medical problem, you could exacerbate your condition by drinking another person's urine. Drinking your own urine will only return wastes back into your blood and force your kidneys to re-filter them out.
