You mean being polyamouros? Well, if the two (or three, or four, five...) parties are in agreement to be in an open or polyagamous relationship, then I think that's perfectly fine. Variety makes the world go 'round. BUT, if they flat out cheat and carry on an affair behind their partner's back (aside from sex addiction, which does exist but that's an entirely different rant.) then yes, they are basically whores.

I'm don't know what path Zoey will choose; the mature polyamouros talk with her committed partner or the sneaky cheating behind his (or her. Hey, never read the book, she could be a lesbian for all I know. OMG WHY AREN'T THERE LESBIAN VAMPIRES?! THAT WOULD BE AWESOME!!)back. Of course, this is all assuming she will get into an 'exclusive' relationship with the first guy she meets, because ALL Sues do that, but I'm going to make my prediction...

...

Zoey will be the most epic slut ever juggling around multiple men behind their backs and not making any one else aware of it, and promising exclusive relationships or hinting towards exclusive relationships with them. Basically cheating. She's going to make fandom Sues look like monogamous pussies. :D
