DH pees sitting down at home. His momma taught him to. Bless that woman

we will teach our son the same.
From what I understand, they can't actually control the flow that well usually (unless their bladder is super full or something), so with a normal toilet there is basically no way they will get it all perfectly in there. Peeing standing up is for outdoors or urinals.
Historical tidbit. It used to be the women were the ones who peed standing up. They had to hold their skirts up and off the ground, it worked better. Men had all their hose and pants and all to pull down and would pee sitting/squatting on a pot more easily. This is what I've heard anyway. I had a girlfriend in high school who always peed standing up and claimed to have perfect aim but I never personally confirmed it
