Well, based on the following, I'm still not drinking it.

Regarding hygiene, let's return to the phrase "relatively sterile". While many sources will tell you urine is "sterile", end of story, this is not entirely accurate. Urine can actually pick a variety of bacteria as it exits the body through unwashed or infected genitalia. While this probably won't hurt you, it is rather icky, so the solution is to wash the area thoroughly and then collect the urine mid-stream. If you've ever had to give your doctor a urine sample, you've already practiced this technique. The moist towelette provided was to remove external bacteria, while the first flow of pee that you let go uncollected was to clean away anything lurking in the urethra itself or at it's opening. As long as the pee you are drinking is your own, this is probably as much as you need to concern yourself with. However, if the urine belongs to your sexual partner or another person (see Water Sports), consider that there are certain viruses and bacteria that can be carried in and transmitted through the urine (such as Cytomegalovirus [CMV] or Hepatitis B Virus). In essence then, if you drink someone else's golden shower, you may be guzzling down a great deal more than you bargained for. More importantly, do remember that even tiny abrasions or tears on the inside of your mouth or on your lips (or on any external part of your body) could allow the virus or bacteria to enter your blood stream and thereby infect you.
