I didn't use the walkthrough, but it should work to a point, the game didn't actually change past events, from what i could see, it's the visuals that was changed not the content, although i didn't play the new version yet or seen the log so don't know about that either, and of course there is new content too that the walkthrough may not cover if it's not updated.
From what i remember there is a scene where you can choose to be dom or sub, in the sub there is femdom content, but it's just one scene that i remember though, and the game at least until now is either you go corruption routes, or a more soft route.
