I've already done that. Its saying you need 10 lust to talk to the warden for the first time but in the previous version you only need 6.
Masturbating at night on the bed, you can raise lust from 1 to 5 (if lust is higher than 5, it will not rise)
Inspection scene at the beginning of the game +1 lust
Scene with Ethan in the Dining Room + 1 lust
Photo shoot +1 lust
Scene with medical examination +1 lust
1 nurse scene +2 lust
2 Nurse Scene +2 lust
