They're tied to slut level but they're only tied to their respective specific slut skill, so for example she'll only go full whorish for handjobs when her handjobs passives are all unlocked. Her vaginal sluttiness will be unaffected by her handjob sluttiness, unless of course she acquires all of her vaginal passives.Can i somehow stop her from going turbo-slut and still get hscenes or are they tied to slut level?
So basically if you want her to not go full slut, just don't let her get too deep into the various slut-skill-branches.
