S asked: If the two of them went away together for two weeks where would they go and how often would they fuck a day?
Ember Island is obviously a place they go to pretty often due to nostalgia and because they did bond a little again when Ozai sent them there, and I can totally see them having their honeymoon there. Ba Sing Se would also bring "good memories" (much to Iroh's dismay).
And Azula would also talke him to Omashu (aka the city she invaded) and Zuko would take her to all the places he went to (and caused mayhem at) during his banishment. Things get awkward pretty fast, but neither of them care. And yes, they've screwed in public places MANY times.
Since they both got high libidos, are absolutely crazy for each other, and they both know exactly what the other likes, they're likely to have sex at least once a day. When they're on vacation, or just have less work to do that they, they'll fuck until the sun is almost rising, and then do it again either right after waking up or some time in the afternoon. On the rare occasions where they have to spend a few days or even weeks away from each other, pretty much everyone that knows them just leaves them alone because they will not let go of each other for ever a second for at least an entire day.
