If you're wondering about my explanation for why she was really horny post inkperial era (again, besides me thinking it was funny at the time) here you go.
Keep in-mind this is only half canon since I came up with it late at night and it might be stupid
The sudden horniness was sort of a coping mechanism. She had spent months in isolation besides EC checking in to make sure she wasn't trying anything. Safe to say he wasn't exactly good company.
Her sudden change in demeanor was an attempt to be more desirable because she was craving connection after months of almost nothing. This wasn't the best route for it but she wasn't exactly right in the head.
Thankfully she ended up with Sap and not somebody else since he actually cares about her
