answer:1. It’s certainly possible, and I’m sure it’s been done on many occasions. 2. It would be especially helpful for said male author to read books by women about women, and talk to women about their experiences in similar situations as his protagonist. I, of course, don’t know how the thought/emotional life of a man (or anyone) differs from my own, but externally I’ve noticed that women are more outward with their emotions, and appear to be affected emotionally more easily than men do. 3. Sure! Creative writing has no limits!
