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.

Get the Porn fidelity mug.
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.
