All these examples describe what happens in the scenario. So asking if it is rape is asking about something other than the scenario itself. The moral opinion of the person being asked, the law's position etc.
The law's position is easy enough to find out from most governments, on the internet at least. A moral opinion is a complex topic in itself, but about the reactions to the scenario rather than the scenario itself. It could also be a semantic question where definitions are simply made up.
Other than that, rape in its modern form is very new. Before the women's sufferage movement, aka first-wave feminism, a man forcing himself upon a woman was generally regarded as something closer to vandalism, if the woman's sexual purity was valued (a virgin or belonging to someone else), otherwise it was often not even seen as bad as that. There were exceptions however, but the modern conception of rape, especially from the 1970s onwards, is quite unique. It's still solidifying into culture, and thus opinions on the matter are changing rather rapidly even now. Most changes are in the direction of those nos to the OP changing into yeses. Certainly the more borderline cases would have been seen as quite acceptable and normal not many decades ago.
