Would you rather hold your poop or pee in for a long time?

Pee, definitely.

If i understood the question right, at least.
Point being, even as a girl i would have it easier PEEING somewhere than pooping... Also peeing my pants, while embarassing, also has an erotic factor for me...shitting into them is just plain embarassing and feels dirty the rest of the way.
it's just the psychological aspect of it, pee puts a lot less "pressure" on my mind than poop.
