Well Fluttershy is always taking care of dozens of animals year-round, and if somepony needs help, she'll gladly gladly help them without a second thought. So if having too much love in your heart makes you a slut, then Flutters is the single biggest slut I've ever seen.
On the other hand, Celestia, act just like a mother who demands her children (or subjects) do everything she asked them to do, as well as everything she didn't ask them to do, but expected them to anyway, and when those unexpressed expectations go unmet, you act all "I'm not mad, just disappointed" to emotionally manipulate the ponies who don't even know what you expected of them.
