@Tenma: It's not completely off topic. In discussion of rape mechanics in games, the definition of rape is important. Also at the risk of stating the obvious, armed services operate in situations where regular law does not apply, and with dangerous equipment/environments, and so your statement is correct: if someone cannot rely on the law to protect them, then safety should be their concern. It's also correct that if the law states someone should be in a safe place (or at least with respect to the actions of others), they shouldn't have to assume they are in an unsafe place. Otherwise there's no point to that law.
@super_slicer: I'm going to point out that for all of those things that you attribute to "feminazis" either they're things which are not true under law (i.e. retroactively withdrawing consent is not possible under any legal system, if only because it would significantly undermine all verbal contracts), or were covered by law decades ago, way before any "feminazis" were politically active (although your terminology is very unclear, but it sounds like you're talking about harassment for most of them, which in the US is 1960's law). As an academic, I'm afraid I do feel an obligation to correct misinformation when I see it.
Tis a shame that no-one has come up with interesting implementations on loss of control though. The Eramaker games (or at least, the ones where you don't play as a Master type character) do some of this, but then again they're kinda not great games even if you do get past the language barrier (very good story generators though!). Also
@Tenma, QTEs as a mechanic for escaping rape have been done before. Like, a lot. Unfortunately, QTEs are frequently cited as one of the worst game mechanics present in popular games, so I'm pretty sure that implementing QTEs in an H-game will annoy many of the players. On thinking about it, this might be one of the big problems with implementing "better" H-game mechanics. I suspect that it's also true that lack of control as a mechanic would annoy a lot of people as well, so even before considering any details about the amount of effort required to implement better H-game mechanics, an author would need to weigh up the risk of alienating parts of their player base by implementing those mechanics. It actually turns out to be a more complex topic than I first thought.
EDIT: Actually now that I think about it, NewLife also does lack of control as a gameplay mechanic (what with it's willpower/drunken-ness mechanics), and it's reasonably interesting implementation of it. It also highlights just how tricky the entire consent stuff is, because despite the author of NewLife not wanting to include non-consent content for legal reasons (which I think he's misinterpreted the law on in a fairly substantial way, but it's his game so he gets to decide what he does with it), NewLife certainly includes non-consent content.
