Not sure what this is called, so didn't know how to search for it (apologies if this is already covered elsewhere). When you are being accosted, there are four descriptions of the accosters feelings? attitudes? positions? They can change in colour after actions are taken. Are these attitudes in a particular order? What do they represent? What do the colours represent?
First stat (eager): enemy health. Self explanatory, this is just the enemy's health bar. It goes from red to green the more you deal damage to the NPC. Once it hits green, their health has hit zero and you're about to win the encounter. It's basically irrelevant during consensual encounters, since you won't be fighting your partner off.
Second stat (stimulated): enemy arousal. This is also self explanatory. It goes from green to red, though most encounters start at teal, not green. Once it hits red, they're about to orgasm. This can be either a good, neutral or bad thing depending on the encounter. If you're just having sex for the sake of having sex, it's essentially a timer.
Third stat (calm): enemy anger. Also self explanatory; how angry they are. Green means they're perfectly calm and happy, red means they're seething with rage. This determines what kind of actions NPCs take. Angry NPCs are more likely to physically hurt you, more likely to be rougher with your clothing, and less likely to accept anything you try to do.
Fourth stat (cautious): enemy trust. This one is less self explanatory. Trust is kind of a lesser version of anger; it doesn't make the NPC any more likely to try to hurt you, but it makes them less likely to follow your requests. It goes from green to red. A NPC with high trust is more likely to agree if you ask them not to take off your clothes, or if you try to guide their genitals with your hands. A NPC with low trust will refuse your requests and ignore your attempts at foreplay.
