I'd stay female...
For all the trouble and bother being female causes, I don't know that I'd be the kind of person i am without every second of every day that's helped shape me for who I am. I also like that there is no particular stigma attached to females being able to express their emotions, whether it's happiness, anger, or sadness... I can cry in public if I need to, and there's not a huge social barrier that says I shouldn't. Also, I think women, in this day and age, have 100% more going for them than at any previous time. I wouldn't want to miss out on those experiences for the world.
