Well, first of all, it can desensitize a person to appropriate sexual boundaries. Since sex stories may contain exaggerated or improper sexual content, it can make a person less sensitive to what is acceptable in real - life sexual interactions. Moreover, it can have a negative influence on one's self - image and self - esteem if one starts comparing themselves to the often - unrealistic characters in these stories. It can also create an unhealthy interest in sexual matters that could potentially lead to inappropriate behavior or attitudes towards others.
One potential negative impact is that it can distort one's view of healthy relationships. It may focus too much on the sexual aspect rather than emotional connection.
