Maybe you are in the minority of simple ready to go females, but maybe you don't work or are in high school since you don't even need a pen? I will say manyyyy females that I know carry something like a k bar, etc snacks. also, do you don't carry a small mirror to put said lip gloss?
I am not in high school, and I do work. Why would I need to carry a pen? Stores have pens at the checkouts. I use the notes app to take notes, or just take a picture to reference later. The handbag I sometimes carry does have a pen at the bottom of it, but I can't recall the last time I actually needed to use it. I don't even know if it works. Shrug.
And no, I don't need to carry a mirror. It's easy to apply gloss without a mirror, or if I'm feeling fancy I can use the reflection off my locked phone screen.
