Questions: Girl's Behavior

My girlfriend has started doing #2 with the bathroom door open more often, especially in the mornings or when we’re home relaxing. She doesn’t always close it anymore.

I have no idea if this is a view the majority of women hold but I've seen women online who are super offended by the words female and girl.

Something about the word female being animal like and the word girl being used to describe children and as such it's dehumanizing when men use those words instead of just saying women.

I do realize the irony of asking if girl is offensive on a site literally called "girls ask guys."

As a man I don't believe I get to have an opinion on it but as long as it's nothing something like "men and females" or "men and girls" then I would guess it's not offensive. Say males and females or guys and girls or boys and girls. But not men and females or girls.
