Ooh, I like this one. I find a lot of emotions attractive, but mostly in how they come together, which is more complex than just answering about the raw emotions. Some manifestations of happiness really get me swooning, and explosive manifestations of anger usually get me feeling things.

If this was meant more as "what emotions draw me in" honestly very similar answer; Joy, anger, the sorts of things that are felt and projected with passion. Fear's a hard one to work around, since it's like talking with a skittish deer, I will say. But all in all, passion and the many emotions associated with it.
