I was recently asked by a co-worker how much time it takes to write a book. Of course, it varies, but I added that I generally don't count the time I prepare for a novel. They seemed perplexed. Prepare? Isn't that book about sex and relationships? Yes, some of my novels are domestic and even erotic, yet research is still required.
The assumption that domestic fiction won't require research is probably based on the perceived content: it's just about ordinary life and sex!
Well, I don't know anyone, even book characters, that have sex 24/7. Characters have careers, some have disabilities, mental illness and a slew of other issues that the author has never experienced. That correlates to research.
Let's look at my most common research elements:
The manner of research varies. Most includes internet searches leading to blogs, forums, articles and then there is the focused research that includes reading non-fiction books (which is where I get most of my information), or getting out there and asking someone! People love to talk about their work, they really do.
I write about: love, fantasy, hate, vampires, jealousy, lust, supernatural, murder, deceit, attraction. And sex.
I write what I like.
