Just my personal opinion as a reader (and all reader opinions are likely to be different): I don't really care to know the actual physical details.
Just as in a horror movie, I don't really care to see the gore of a knife slashing open someone's flesh.
What interests me the most is the emotion. The suspense, the fear, the denial, the feeling of helplessness and despair.
Here's a quasi-rape scene (I use the term "quasi-rape" because it's more like an unexpected seduction / betrayal, where he seduces her and then only afterwards does she feel she was raped), by Jennifer Egan. Notice how she doesn't dwell on the actual act, but just gives a few glimpses here and there.
In my opinion, the reader's imagination is a useful tool in visceral scenes. Sometimes the more you leave out, the more the reader can fill in the gaps. If you put everything out there up in the open, it can become clinical and "sterile"... But if there's a sense of mystery about it, leaving things up to the imagination, it can seem more awful, because of the very things that are clearly going unsaid.Originally Posted by Jennifer Egan
Just my two cents. Brave of you to tackle such a subject in regards to your past. Hope all goes well with it. Cheers
