This? Girl this? This is called fashion, look it up.
I don't want to have to fuss with any buttons when I've got to peeeee!
If I have to pee or remove my pants for any reason, I could just unzip it rather than struggling with the buttons.
Well. Let's just say that I NEVER got my pecker caught in button fly jeans. Enough said.
ONLY because the zipper can get stuck. Never had any bad experiences with button up jeans, but have had a couple "sticky zippers" with zippered jeans.
