That was sort of my fault. I had no way to deal with goblins, so I just let them slut her up until they died.Totally depends on what you're looking for.
Ingame tips?
First, the obvious one, don't let her be a total slut, but it's probably too late for that isn't it
The main factor is endurance. If you level that up and use edicts/accessories to increase it you take less pleasure damage. Staying on high stamina in battle to some extent, too. The exact damage ofc also depends on your enemies, but you can't change them.
Modding tips?
I (and others here) can most likely help with that, if you specify what exactly it is you want.
For modding, I want her to be lewd dominant. After attempting to go full lewd because I failed at no lewd, it was 4-5 hrs of grinding to get her to become lewd. I was really hoping for her to actually be a sadist or be proactive, but she's really passive towards it.
