I'm curious to know why every time the Doctor regenerates it's a new guy, why hasn't a woman played the role of the Doctor yet?
GO AHEAD, RIP ME A NEW ONE, I DON'T CARE ANYMORE!

I'd just assume that it's because the Doctor is a male character. He can have all sorts of variations to him, and I don't even think his changing skin color would be an issue. But at the end of the day, the Doctor is just inherently male.
