Sometimes you get hung up on a sex scene or an action scene that keeps you from finishing the book. Don’t. Put in a placeholder, just like with the names mentioned in the previous post, and keep writing. Just make sure to go back to the placeholder later.
The placeholder can be something simple — [sex scene here]. Or something more elaborate [sex scene where hero gets smacked before they get hot and heavy]. It’s just a quick note to yourself so you can continue writing rather than staring at the cursor while you try to think up a sex scene or action sequence. If you use brackets, you can always use the Find function later to go back to the spot.
