How to Write a Sex Scene

If you want to write an excellent sex scene, you have to liberate it from the idea of a sex scene. Like I was saying before about violence, you have to thread sexuality through every part of a character or a person's life, rather than limiting it to a titillating few pages where something juicy happens. You have to understand that sexuality is omnipresent in your body — your entire life.
