I sit to pee... like... 99% of the time. Idk, it's just more comfy and has always felt more natural to sit... seemingly more so recently. I mean, I can stand and do it I guess... if I have to use a public restroom and the only thing open is urinals, sure, or if everything is dirty... but it is never really 'comfortable' peeing like that, and not from a dysphoric stand point either.
