I always do it, but just remember, it's not good etiquette to do it BEFORE you get to the water 
especially if standing on concrete
steamers in steamers eh!.
dont have the problem on a salt lake , but dont run your front wheel over the yellow salt patches.
If you see a small dark object on the lake, dont sail too close to find out what it is
I dont discriminate and pee everywhere
Buses, lamposts, trees wetsuits its all game....its the beauty of being man.
slightly off the subject, but , EVERYTIME i drop down the hill into Lancelin and i see sand being blown off the dunes and waves breaking way out back....it makes me want to crap, even if i unloaded before i left.......
and the dunnys are so bad in lano
I try not to. I hear it's bad for them. When i'm kiting along in my springy, i just flop it out of the leg hole, and pee as i ride. It's good.
I can do it surfing, while in the water waiting for a wave.
But have never been able to do it while riding at 20+knts, I have to stop, a good excuse when I crash or mess up a gybe. And then like Mark, wash it down with some fresh water.
Can you wee while riding?
A quote from this forum some time ago comes to mind
"Handle every stressful situation like a dog, if you can't eat it or hump it.
Piss on it and walk away"
BEWARE the back-pressure if you stack in a bloated, sealed wettie!!
it will squirt out your eye sockets!!
I seem to remember reading somewhere a while back about pee-jibing..
Ah, yes.. there it is - Cammar up to his usual tricks:
Well a pee push loop would not be nice probably come out around your neck
A pee air-taka DTL and landing on the wave would be the hardest move I could think of
especially if standing on concretehowever when on concrete make sure you're still dripping wet when doing it as to camoflage the event
what about poo poo who does poo poo in there wetsuit 
i know a kitesurfer that did
Awwwe you guys
And so ends my contribution to this discussion before I discover new unplumbed depths of self humiliation
