I want to jump on the train that this is a quality game.
The game is taking its time, but that's fine. It's important to not give away the goods to soon or people lost interest. Saying that, you need some sexy content to keep people coming back.
Note if you want to add in some sex scenes but not add into the relationships of the people yet, you can always have a party where she gets drunk and hooks up with a random person. There is also an app called Tinder too LOL.
Saying that, this game has shown these developers have good judgment, so don't force anything to keep a few vocal people happy. Stick to your vision.
