"On the one hand, sex can be tranformative. In fiction, it can serve any number of essential purposes.... But on the other hand, it’s just two people rolling around on a bed (or in a woodland glade, or against a wall, or wherever). And while they’re doing that, they’re usually not catching serial killers, or learning the terrible secret of their identity, or fomenting the French Revolution, or whatever else they might otherwise usefully be doing. A sexual encounter might be essential to the plot, but often the plot has to stop and stand around twiddling its thumbs while it happens.... If sex isn’t actually necessary, then don’t...um, shove it in." - Sophia McDougall on writing sex scenes.
