So, let me paraphrase your question because it is complex, worded confusingly, and I want to make sure I am answering what I understand it to be.
Q: in movies and books, when a person has an emotion that overwhelms them, like rage, anger, or sadness, does it manifest, continue, and even carry itself into completion in a sexual experience?
A: I have to assume you are referring to the Dominant person’s role, since they tend to be the one leading the direction of where things are going (i.e. will it be rough, or soft, or whatever).
Well – I don’t know, but I do not believe sexual emotional experiences and precursive nonsexual emotional experiences need to be related, and may not be entirely healthy if they are. Case in point: if I am super anger and pissed because something horrible happened to me, I don’t know if it is the best thing to go hatefuck somebody and use them as a cathartic release.
Catharsis, in general, is a disproven psychological idea when considering it’s benefits, which are more perceived that actual. I think angry sex should be responsible.
Q2: Now I may have misinterpreted the question, because “where one person is so overwhelmed by emotion … that when they see their person they have sex [with???] and it’s some emotional release for them.”.
This question is totally different, and with one word, changes everything. Did you mean, “When you witness your partner fucking somebody else, does it carry a emotional release for you?”
Was this the question?
