Make a self-control roll whenever you have more than the briefest contact with an appealing member of the sex you find attractive, at -5 if this person is Handsome/Beautiful, or at -10 if Very Handsome/Very Beautiful. If you fail, you must make a “pass” using whatever wiles and skills you can bring to bear.
Make a self-control roll each morning upon awakening. If you fail, you suffered nightmares; this costs you 1 FP that you can only recover through sleep. On a roll of 17 or 18, you are left shaking, and are at -1 to all skill and Perception rolls for the entire day.
