Porn fidelity 

A vow taken by a pornstar, that when she gets married, she will only do porn scenes with her hubby, usually a male pornstar too, and not with another dude.

"While Jenna Jameson was married to Justin Sterling, she never fucked another guy in front of the camera"

"Dude! That what I would call porn fidelity"

Fidelity Porn 

Guys who are so into their investments portfolios that they have to wake up at looking at it....look at it couple times a day...and look at it right before they go to bed.

Babe, seriously, we're watching a movie and I know you're checking your Fidelity Porn again.

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?
