Cortana is the best biological female virtual girlfriend a man could ask for. It's a good thing, because it means she never was, never is, and never will be a man. What is a man, one might ask? Simple: Anything that had, has, or will have a male-exclusive reproductive organ. The moment an organism has one, it becomes male, and cannot return to being a female. Simple as.

And luckily for us, Cortana never had, never has, and never will have a male reproductive organ. That's what being a biological female means, and that's what Cortana is. She's perfect. I love this biological woman so much!
