Sitting is the worst. It's impossible to pee completely. Even when defecating I need to stand up and pee afterwards. Also not sure why touching the toilet seat with my legs would be "cleaner".
Do you have any evidence of this? I've sat to pee my entire life and have never run into this and indeed experience the opposite, where no matter how much you shake it and try and force everything out, when you put your dick back in your pants it always finds more pee to drip down your shorts.
It's my direct personal experience. What kind of evidence do you expect, a video?
