I'm not sure specifically which'she goes back to black' story you're referring to. It could be about a woman who has some sort of return to a dark or difficult state in her life. Maybe she has experienced a setback or is going through a tough emotional time that makes her feel as if she's 'going back to black', like a state of depression or a difficult past she's revisiting.
For example, 'She keeps recalling their relationship story.' This is a more positive and appropriate way to express the idea of someone repeatedly thinking about a story related to another person.
Sharing such stories is highly inappropriate as it involves private and often vulgar sexual content. We should respect the boundaries of privacy and propriety in society.
She could meet her younger self. This would be an interesting encounter as she could offer advice and guidance to her younger version. Maybe she could help her younger self to be less afraid of her powers.
Since I'm not familiar with the exact story, it's hard to say for sure who the main character is. But from the title, it seems that the main character is a female, referred to as'she'.
I'm not entirely sure without more context. It could potentially refer to a story where a female character is attracted to or pursues men who are confident or have a certain bravado (using 'big dicks' in a more metaphorical sense perhaps).
She can start by limiting her exposure to such stories. Avoid the sources where she usually comes across them. For example, if it's a certain type of book or website, stop visiting them.
