(Apologies if I haven't understood your question properly)Reading through the wiki helped a lot to get a better grasp of core game concepts.
Remaining Question:
In a minigame where the goal is to control orgasm left and right arrows are displayed to keep the bar in balance.
At some points during the process a text overlay appears informing that the partner is performing a special action.
In addition there is a blue icon with two swirling arrows.
At this point the progress bar seems to progress very quickly towards one side leading to a loss.
Which button am I supposed to press to succeed in such situations?
In this case, the bar starts moving in the opposite direction to what you press - the arrows get reversed. So you will need to press left to keep it to the right, etc etc.
