It can bring readers a rich imagination and emotional experience through direct description, metaphor and psychological description. From an artistic point of view, sexual descriptions could improve the artistic effect of works by attracting the attention of readers, arousing the resonance of readers, and shaping the image of characters. In some excellent literary works, sexual descriptions even became emotional descriptions, psychological descriptions, environmental descriptions, and other aspects to make the works more complete and profound. However, in literary works, sexual descriptions also need to pay attention to moderation and restraint to avoid excessive exposure and inappropriate descriptions so as not to affect the value and meaning of the work. At the same time, sexual descriptions should not be the center and only content of the work, but should be balanced and integrated with other aspects to make the work more integrated and coherent. Therefore, the sexual descriptions in literature should be judged and evaluated according to the specific situation. We should respect the artistic effect of the literary works and pay attention to avoid excessive exposure and improper descriptions to maintain the dignity and elegance of the works.
