SQ, I'd argue with people not describing rape in films as sex...
I need to find an example, but I think Waitress may be an example. If we define coercion as "nagging" a woman for sex, using words, force, threats, etc, then there is a scene in Waitress where Keri Russell's character is raped. Yet, so many people I know described it as "sex".
Remember, until 1990, the law didn't recognize that a man can rape his wife. We have this mainstream image of rape pushed in our face, so that once we're confronted with the reality, we don't identify it as such.
It took me ten years to identify my first rape as such. (TBF, I'd suppressed the memories for most of that time) It took me four years to realise my son was possibly conceived through rape. Because the media pushes this image on us that if your rape isn't violent, or carried out by a stranger, it's not really rape.
