I write from a female PoV a lot, I tend to do it more than a male PoV. I have no idea why, it just seems to fit. I can't really offer advice here, because it just seems very natural for me and readers seem to agree. Not entirely sure what that says about my masculinity

. What rollin said is very pertinent and it applies equally to either gender. The tone has to be right dependent on when the story is set and what sort of person you're writing about or whose point of view. Research can also be important. I tend to set the stories in settings I'm familiar with so that cuts down on the research, but I've done one large historical piece and I had to research that one, I also reread A Christmas Carol when I wrote my own spanking take on it last year.
