I used to write a lot of stories about being put in a girl's body. Sci fi stuff, mostly plot outlines and setting concepts than any actual writing.

My favourite was one that was set centuries in the future, a setting where people could control their bodies however whatever...

...the main character by circumstances (conflicts and happenstances) was a guy who became stuck in the body of a woman.

This character was in a world surrounded by others in a world that wanted him dead if they found out he wasn't actually this woman for real.

So he faked being this woman...

...as a means of survival. Acting and immersing as this woman, being her and feeling her, becoming her.

To a point she was her. A point where more of her was her new self than that past beforehand.

She was this woman...
