1) It is why some perks have been introduced. Bambi locks you at 40 max confidence while being all timid, Broken also locks you at 40 max but able to agree to all sex encounters.
2) Broken perk is as close as you will get. But I will never depict forced encounters as anything but bad.
3) Latest build has switched this to a perk where you can see how long it will last
4) There are some conditions where it can switch dub-con to con, but no enjoyment of full on non-con.
5) Motel job (eventually) will have this.
Recovering perk is my simplistic way of portraying both mental and physical trauma. Not something a psychologist can solve and it only really triggers when something pretty traumatic happens. But as mentioned above, it is now a perk where you can see how long it will last and can be blocked entirely by the "numb" perk.
As mentioned above, switched to a perk where you can see how much time is left until it goes away.
Not in yet, but once you get to know them better, it will display their personal stats and encounters. Sammy would in reality never know this stuff but it's fun for players. It will show their own personal stats as well as stats specific to Sammy.
