Sex Likewise, erotic books do not turn men into rapists. Just the reverse, in my opinion. The more subtle the sex scenes, the greater turn-ons they become. Sex should come naturally in a book, the writer should not even contemplate putting it into his synopsis. However, this is as good a place as any to discuss it.
Contrived sex is as obvious as gratuitous violence to the reader.
There are no hard and fast rules concerning whether or not adult books should contain sex. It should depend upon the relationship that exists between two people in the story. Sex at first sight does not ring true. Situations will develop and the writer should weigh up whether or not to portray a couple in a sex scene and, if so, how to describe it. Terror is not conducive to sex so a man and woman trapped in a haunted building throughout the nocturnal hours would be most unlikely to copulate.
