HAHAHAHA!!! I am dyin' over here!! LOL!!
It really is a great question though...
Also, what is sensual or erotic about this? I mean, urine is just not a turn-on. Is it? Weren't we just discussing the virtues of some pinapple juice so that one's junk is not stank? Does anyone find urine to be a pleasant smell? (I know mostly it is odorless, but when it is all over you, I'd imagine it would be somewhat stank). I just don't know man.
The freaks come out on GC, I tell ya!
