The first in an occasional series considering various technical aspects of our literary craft
My headline for today has, I suspect, lured you here under false pretences. I've only ever written one sex scene, and that of a very indirect sort. It's not a branch of literature, in general, that I admire. This arises not from prudishness but from a perception that such scenes very rarely add anything--beyond risibility--to the reader's immersion in the fictional world.
The first question the writer needs to ask is "do I really need a sex scene at all?" The writer is creating a construct, an imaginary world, by choosing which details to set in front of the reader, and which to omit, or imply. Introducing a sex scene is therefore a conscious choice by the writer. There are many ways of conveying to the reader that characters are in a sexual relationship; there's no need to depict the act unless it adds something to the reader's experience.
A sex scene can be justified, it seems to me, for one or all of the following reasons:
- the relationship depicted is the central point of the novel
- the scene is revelatory of one or both (or more--orgies are within the scope of the discussion) of the participants' characters
- it provides an emotional counterpoint to events immediately before or after the scene
- it provides comic relief
At the other end of the scale, do you prefer anatomical precision? There is a comparatively limited gamut of what can be put where, and in what sequence, but at least this tactic avoids coyness.
Analysts of the sex scene will be interested in how the author chooses to refer to what Jack Vance called "the frontal member". From this one choice, the tone of the rest of the scene will follow. The choices are (with variants, of course):
He, Him
As in "she felt him inside her, a pulsing warmth etc etc etc". Under this approach man and member are one, indistinguishable and indivisible. The point of the scene may be to demonstrate precisely that fact about the protagonist's character, but more usually it's a default setting for the writer who's keen to display sex on the page without the indelicacy of listing the anatomy involved.
Penis
Medical terminology is occasionally used to avoid the oblique obscurity above. Unless the writer is trying to convey a clinical and emotionless coupling this is unlikely to be successful.
Cock
Slang terms--there are of course others--are often used to convey an earthy immediacy, and can deliver anatomical precision with emotional intensity. The main danger here is that the language is so alien to the voice of the rest of the story as to jar.
There is an annual 'Bad Sex Award' "to draw attention to the crude, tasteless, often perfunctory use of redundant passages of sexual description in the modern novel, and to discourage it". In this latter aim it appears not to have succeeded--indeed there is a perverse kudos to winning it--but it does illustrate that a bad sex scene stands out with priapic prominence from its surroundings in the way that, say, a bad fight scene would not. Your sex scene may be fully justified in its context, but if you can't write a good one, you are still setting yourself up for an embarrassing failure.
In creating the illusion of a fully realised fictional world in the reader's mind, the writer is making a series of choices about the scenes to present. Your reader will fill in any gaps you choose to leave. When considering a sex scene, more than anywhere else, you should ask yourself whether you can do a better job than your reader's imagination before reaching for the literary Viagra.
