One day I woke up in a girl’s body and never changed back into a man.
Since I’ve experienced it both ways, I can tell you as a fact that it’s a ton easier to run as a girl than as a boy.
It’s so much more comfortable without a penis and balls in the way. I never realized how annoying they were until I experienced having a female body; now I don’t know how I ever lived with all that shit hanging down there. It’s such an improvement, even if I could go back to being a boy, I wouldn’t.
