I'm a trans girl and I love peeing where I shouldn't
Why would you like to pee where you shouldn't?
I don't know, I just love pissing on people.
It is unsanitary to urinate in places you shouldn't. It is even more unsanitary to urinate on other people, especially without their consent. That is actually probably assault, so you should stop doing that if you don't want to get in trouble with the police.
If they catch me pissing on a person, I will deny everything.
You can deny it all you want. The proof is that a person now has your DNA on them because you urinated outside of a proper restroom.
