I think that this is a muddy topic that gaming doesn't deal with very well. Is it "consensual" to be able to talk a specific character into boning you by using walkthroughs/guides/etc and does it gamify sex? I don't particularly have the answer but I've had great discussions on it.
I've personally never understood how the question of consent comes up in these discussions, we're dealing with interactive fiction, everything happens subject to our willing disbelief and is help by the illusion of choice, that said I'm very much against the kind of writing you're talking about that treats relationships as very one sided, with rare exceptions in RPGs you are always the active participant in any interaction with your companions, and since the advent of "friendship points" a very unrealistc meta-game around relationshipping takes over from what should be something driven by roleplaying, you know like you would hope would be a big part in a (R)ole(P)laying (G)ame *sigh*
