Peeing in the sink
Pissing under the shower is very wide-spread. But who else uses the sink? I highly recommend it, at least for guys. It's probably less convenient when you don't have a dick.
It's (potentially) very clean, even more clean than pissing in the toilet (while standing up), because you can't possibly miss, and there's less area for the the little droplets to cover. I personally go a little further and hold my off-hand over the end of my dick like a shroud, to absolutely make sure that no droplets or mist can go anywhere but down, and potentially hit the soap/toothbrush/etc. Then I just rinse off my hand, my cock, and splash some water inside the sink to rinse that off too. Don't try to save too much water, because you have to flush out the trap. If any urine remains in there, it will start to smell. Also, even if you don't clean the sink properly afterwards, who really cares? It's not like you're eating out of there.
It's very convenient to piss in the sink. You can use it during the night without having to turn on the light, because you can't possibly miss. You can piss into it while having an erection, which would make it very difficult to use the toilet. You can even piss into it hands-free, if you so please. It's not as much fun as peeing under the shower, but you can do it at any time.
I started using the sink as my toilet when my actual toilet was broken for almost a week. I've read about pissing in the sink before but never tried it. Well, now I had to. I ended up enjoying it so much, that from that point forward I used only the sink for pissing into, even after my toilet had been repaired. Well, at least for a while. The novelty wore off eventually, and with it the feeling of naughty pleasure, of doing something you're not supposed to do (although there's really nothing wrong with it). So I mostly reverted to my old habits. I only piss in the sink from time to time now.
I have actually tried out the kitchen sink too. Great fun, especially when there's dirty dishes in there. But it's something I rarely do. For one thing, it rarely enters my mind. I instinctively go to the bathroom when I get the urge. And with the kitchen sink, you really should clean it properly afterwards.
Also, I feel I need to mention that I've only ever pissed in my own sink.
