I allready commented on the other thread with what I am going to say here about it but thats ok.
I have done it plenty in the past, but now days..no it doesnt turn me on all that much anymore, quite the opposite in fact, though I do like to watch a man (especially if I get to hold his dick) or woman piss, and I love being watched when I piss, additonally I am not all that big about having them do it on or in me or me on them.
That being said, if its your kink...keep in mind, that alltough pee is sterile when it initially exits the urethra, it doesnt take long at all for bactieria to start a growing in it, (few minutes is all it take to get harmful levels started) and if your partner has a uti of any kind or other type of urinary related infection... well you just swallowed it.
Also, in large quanities, one should keep in mind that drinking pee can lead to some physical/medical problems including dehydration and possibly kidney failure due to the particulate count being way way higher than water not to mention other things involved with re-up-take of urine to the exclussion of other liquids.
How much is too much for a person can vary to some degree.
Moderation is key. Small sips people. lol
Have fun and be safe.
