Do you have an equal balance of male or female characters in your novel? I have eight characters in my novel, which I believe is fine for historical fantasy. Four are male and four are female. The protaganist is male.
What influenced the sex of your characters?
The book that I have just finished writing has a female as the main character. The book is a collage of a number of episodes in a span of fifty years. That has enabled me to bring in at least four additional secondary female characters. All my female characters tend to be basically beautiful with personified female attributes and having the qualities of inspiring their male counterparts.
I really enjoyed writing this book. Found myself weeping profusely while I wrote - sometimes at the melancholy of the situation faced by the main character and most often because of the surges of emotion the story brought out in me. I could do that without restraint because my wife is out on a foreign assignment and children out on their own job postings, had my privacy to let myself be swept away with the story. Good fun!
My MC is female as well, but I do have a male counter part who is her best friend. I've never had trouble writing from the male POV, so I'm not sure, but I really do enjoy it!
Jane Austen wasn't married so there was a lot she must have had to come at by intelligent observation, listening to real life around her, empathy and instinct. The Professor...I first read it as a teenager, and was never quite convinced, but put this down at that time to the Victorian thing. The MC did seem exceedingly cerebral and fastidious in his observations of the young women he taught. Not much testosterone in the mix at all. No libido.
My MC is male. Some aspects of him are me, some are like my brother, some are just his own that came with him. But for most of the story, he speaks in the third person, so it's mostly a question of being aware of phrasings he probably would not use. My mother is worried I might write him some lurid sex scenes, so to torment her I say, what a good idea.
