I write and conceive of stories from both POVs, but my current WIP has a male protagonist, and it's really comfortable to me, maybe just because I feel like I know my own characters so well?
I am pretty comfortable writing in the male POV, however, whereas I suspect many men would not be so comfortable writing in the female POV. Similarly, as a caucasian person, I am uncomfortable writing in the POV of a POC, whereas I don't suspect (but I could be wrong) a POC would be uncomfortable writing something from my POV.
I think it has alot to do with what we conceive of as the "every-man". I have little problem appropriating the white male POV, because on some level, I see that POV as a blank canvas. Now ideally, any POV should be able to be a blank canvas, because I think we are all human beings first, and whatever other qualifiers are stuck to us second. But I think it's generally true that the white male gets afforded the status of just "person" while everybody else is "______ person", in the collective subconscious.
I wouldn't expect a man to be as comfortable writing in my POV, because my POV comes with cultural baggage that his doesn't. Similarly, I'd be hesitant to try and express my ideas through the POV of a black woman, because there is cultural and ideological baggage that comes with that POV that I am not equipped to handle. I don't like that it feels this way. I want to be able to write about the human condition from the POV of any human being, because again, we are all human beings first, but I think it's a subconscious thing.
So unfortunately, any time I find myself wanting to write about something that doesn't directly relate to some "women's issue" I find myself gravitating towards to male POV, as though this is the best POV to express anything human and universal. Like if we all shucked the extra layers of cultural suppression and bias, we'd all just be white males underneath. The white male is the newborn baby of story-telling. He can be anything you want him to be.
Recognizing this, I think I'm going to try to get away from this thinking.
