Thank you. drained I understood but thought "too deprived" was keeping me from finishingIt's not an issue. It simply means that your sexual relationship with a character is already so high that the specific event doesn't give you bonuses anymore.
Since not all events were added at the same time, you can already have too high a value for a new event, while those you used and abused a lot of times become "drained" for the same reason.
