I never think about the actual process of writing. I suppose I have a superstition about examining it too closely.
There's surprisingly little difference between writing from a male angle and from a female angle, but I feel more restricted in my language when I'm writing as a male character because males tend to sound less emotionally expressive than females.
The first-person viewpoint is more enjoyable to write, because it lets me meander more freely, and it can reveal more of the character's self-delusions. Really all the advantages are with first-person, so I'm sorry I don't get to pick and choose.
