I'm not peeing on the floor, I'm peeing on the shaggy pee mat. Hence the name

I don't understand your question. You're asking how I suck at aiming if I am peeing on the floor, but I never said I was missing the pee mat.

Do you have a penis? The stream can start off rather unpredictably. Especially in the morning, or post-coitus.

It's not like the direction it's pointed and the direction it goes have any bearing on each other.
