What was your first crossdream and how did you respond?

The myth says that male to female crossdreamers do not dream about being women until puberty. Indeed, some cannot remember childhood crossdreams (though that does not mean that there weren't any), while others do.

In this thread over at Crossdream Life crossdreamers tell the story about the first time they fantasized about being a girl or woman. Maybe you can add yours?
