As I can see, and this is my point of view too, the overwhelming number of people in this thread, are here because your game has excellent renderings (imho), some gorgeous characters (e.g. Ellie, Julia), a hot scenario and a fantastic teasing build up!
Only a few do see this otherwise! And the overwhelming number of people complains not about these points, they complain because of the long waiting time and the amount of content. That's just all!
Most of the people are just disappointed because they are eager to see the story move on. I am not explicit critizing the lack of sex scenes because teasing, build up, are perfect, imho. But the intervals we get to see new material is way too long!
If no one would be interessted in this game no one would complain about it. But there are many many fans of your creation and they just want to see more of it. That's something positive!
Or you can say, you do everything right with this game. Just try to do it faster
