Hint. There are two kinds of people in the world. Those who can't aim, and those who haven't realised they can't.
Really, the big problem is
starting. Unlike a well-designed teapot spout, the initial exiting spurt
can be unpredictable, especially if you're bursting and haven't the time/patience/self-control to start with[1]. After that (assuming you're voiding any significant amount of liquid) the biofeedback works wonders. I find, at least.
(I'm writing here from an "uncut" perspective... is the exit hydrodynamics significantly different with those lacking? Well, I suspect the only people who know are non-infant recipients of the procedure, but I wouldn't want anyone to 'out' themselves if they don't want to.)
[1] If I'm in a strange house and
really don't want to cause an accident, but have a feeling that it's going to potentially go awry, I could be probably found[2]
kneeling in front of the pot, to ensure as much of the angle-of-area as the the initial escapement might possible fly towards is already "in the pot". A rather awkward way, I suppose, of ensuring the same advantages as just sitting down in the first place, it also naturally helping with the noise/splashback-abatement policies, of which I mentioned.
[2] Should I not, for some reason, have locked the door behind me!
Or maybe you have bizarre alien biology and don't pee?
Well, you know how Mork From Ork
drinks..?
