Hard to pick just one girl.... all of them have something unique you can't resist to like
I kind of tend towards Luna, she has something mysterious. On the other hand Nancy is very open minded when it comes to other girls and loving more than one person.... which can be a good thing as long everyone knows and is ok with it.
In my opinion there is a difference being a slut (male/female does not matter in that case) and being in a relation with more than one partner.
I guess I am also a little open minded in that regard.... even if I always had just one partner
