I have to say I am firmly in camp B, I have been peeing outdoors since childhood and have no issues. I much prefer going out doors especially when the indoor bathroom situation is less than optimal. I am not a big fan of public bathrooms
I can understand however how many would be annoyed with the sprinkling situation, and squatting if you have bad knees. I was not happy about it either, but over the years I have made some "adjustments" that have helped and made peeing in the outdoors much easier. The first is the whole squat position. You do not necessarily have to completely squat down. I have found that standing with legs wide apart and leaning your torso forward and thrusting your hips/buttocks back (with just a slight bend in the knees) works just as well. Knee problem solved. As for aim, I agree with one of the comments above that "pushing" more will help. But also, and I am not really sure there is any delicate way to say this so I won't bother, it helps if before you pee, you "spread apart" parts of your genitalia with your fingers. As females things tend to get sort of "bunched up" and hence aim issues arise. As for clean up afterwards, I just use mullein leaves. We have a lot of mullein that grows on the property and it makes for excellent natural toilet paper. We have a bidet in the house so it makes it easier to clean up after.
