Rape fantasies are nothing new, but I've never heard the term "non-con" before. It's fine if it remains a fantasy and nothing more. On the subject of cultural attitudes, though, I feel like an abundance of that type of content is a symptom (or reflection) of elements in a culture rather than stuff like this necessarily contributing to it becoming a reality.
Short for non-consensual. Also forced. The responses are higher for nc/forced and lower for rape even though the terms refer to the same thing.
