Polyfidelity

Like polygamy but you don't have to be married.

I'm with Sandy and Anna. But it's not infidelity it's polyfidelity.

Pornfidelity 

1. unfaithfulness in marriage or relationship caused by the act of wife bringing home ass for the husband / boyfriend; threesomes, orgies. 2. belief of person or persons that marriage is not monogamous, boring or repetative.

My girl picked up a chick at the mall, brought her home and we had a threesome! That's Pornfidelity!

There is a website for an example. Wish your girl had that mindstate?
