Writing requires a certain amount of self-examination. The reasons why have to do with the fact that good writing--or dare I say it--great writing requires the author to put something of themselves into the story. If you're unclear on what I mean, have a look at Writing What's Real by Christie Yant over on the Inkpunks site. Speaking from personal experience, she's right. Writing does require intimacy and vulnerability. That's what makes it so brutal--this being open. Self-protection isn't really an option. Criticism is part of the gig. In this age when anyone can call themselves a literary critic without any qualifications to do so, nor any sort of required standard for their criticism... it's even tougher. It's not easy being a real, flawed human being in public.
When I signed on with my agent he asked me a question. "Why do you write from a male perspective?" It was a good question. At the time, I thought it had wholly to do with my desire to be taken seriously as a SF writer. For the record, I still have to fight Romance genre prejudice just because I'm a female. For example: the first question I'm asked when people discover I'm a writer is a variant on the "which type of Romance or YA do you write?" Male writers aren't asked that question and even if they are, they aren't asked it in the first three seconds.
That said, because of my agent's question I pay attention to the gender of my point of view characters, and I've noticed a pattern. If I'm writing Fantasy, I tend to favor male point of view characters. If I'm writing SF, I tend to write female point of view characters. The reasons for this are many, and I'm sure I haven't discovered all of them. I don't necessarily feel this is a good trend to have, but it's there. Part of it is that I associate Fantasy--even Urban Fantasy--with the past. Let's just say being a female in the past wasn't a hell of a lot of fun, at least that's been my impression. When I write about female characters in historical settings I feel I have to ignore everyday issues that I don't need to avoid in the present and future because they have solutions. Things like birth control, menstruation, and well... basic human rights. Right or wrong, part of me feels I have to re-write history when I take on a female POV character in Fantasy--not because of the fallacy that women didn't exist in the past, but because most of our (women's) history has been obliterated. I have so many more freedoms than my Great Great Grandma had, or even my Grandma--this in spite of the fact that so much more work needs to be done. To be honest, I find it difficult to identify with women in the past. What was it like then? Really.On one hand, to focus directly on issues like birth control and menstruation is incorrect. They are everyday problems. They'd be in the background, no matter how life-threatening. Women are people, and people have a tendency to accept things they don't have the power to change, after all. On the other hand, I don't feel right just plunking down a modern point of view into a historic setting. It feels like a lie, and I hate that kind of lie. It does modern women a disservice. It pretends that things were different than they were. It pretends that women don't have anything to worry about regarding human rights because it pretends that there never have been any problems. I hate that every bit as much as I hate it when women aren't portrayed at all--even in the background.
So, I find it easier to write from a female point of view in future and present stories. For now. Obviously, I need to work on this. It's another hold out of the internal misogynist that was installed at birth--and yes, I have one of those even if I'm a woman. Do I hate that? Hell yes, I do.
 I've been criticised for things like "How dare you write a book where a mother doesn't tell her son everything about his father! Especially when his life is in danger!" In real life, families are like this. I still don't know my real grandfather's full name, and I don't know a damned thing about him either. Is this life-threatening? When you consider I have no information regarding that part of my family's genetics/medical history, it could be.
 And having babies is life-threatening and becoming more of a problem in the US.
 See Quest for Camelot. While I was one of those little girls who wanted to be a knight when she grew up, I can't bring myself to watch this. It just seems offensive. I feel much the same about Milla Jovovich in the recent Three Musketeers remake.
