Nothing worse than recounting events with a filter so your readers might not experience the authenticity of the scene. I know it's fictional characters, but sexual abuse minimized to lessen abuse porn feels dangerous, especially for those who've experienced abuse. When I mentioned victims, I meant the readers who will surely gravitate toward this book considering the topic.
I suppose it depends on the focus of the story and on its time frame. Is it about a child escaping from abuse thought their own agency? That's a different kind of story than one who focuses on a victim who has already escaped and is now dealing with the emotional fallout in their life, even if their life is now ostensibly normal.
Regardless, fiction isn't really meant to be simply a realistic portrayal of events. It needs a protagonist who overcomes obstacles to achieve a goal, or to discover a new goal, and it needs to be a goal the target audience can ultimately get on board with. If the story just shows a victim suffering unrelenting, graphic abuse, day in and day out, with no plot advancement, or resolution--with no change--this may be
realistic, but it's not really a
story most people would want to read. I certainly don't think it's something most abuse victims would gravitate towards either, though I can't speak for everyone. Graphic scenes of violence can be very triggery for survivors, though, and they may not be your target audience.
Also, as per how the abuse is perceived at the time, even an abuse victim will notice specific details about an assault--like the smell of their assailant, in addition to the pain and humiliation. Other details can blur.
