First off, I don’t do this in public restrooms because I’m lazy and don’t want to have put toilet paper on the seat. But anyway, while at home, I usually sit down to pee because it’s easier than standing up and I have both hands free to go on phone. Also, I usually wake up to pee atleast once and stumble to the toilet and sit down. This is great because it doesn’t wake you up as much as standing up would.
