When a friend forwarded a link from Lit Reactor on Writing About Sex, I read it eagerly. It contained a few good tips on ways not to embarrass yourself while in the act of writing about the act.
However, the same night, I found myself putting the finishing touches on a sex scene in a novel, and I thought about it more deeply. Why did I have this scene in the book?
Unless the plot hinges on it – which it sometimes does in the case of infidelity or sexual obsession – I realized that a sex scene provides insight into your characters, and what they are like in a primal and, sometimes, vulnerable moment.
Sex is an intimate way for you and your readers to get to know your characters.
