Bet not sooner than 0.5, since this game have a lot of gameplay things to fix/add. For example optimization (I really wish to see Render Distance in settings) and sex is rather a very big bonus than goal itself. But I believe once game will be close to release (assuming it's beta right now) we will get not only cum and squirt but also voice acting and list of different animations.
P.S. It's just my opinion
