look up any word, like donkey punch:
 
1.
An exclusive relationship with your porno collection.
Me, single? Well, I am in a pornogamous relationship with Chasey Lane right now.

2.
The practice of only fapping to one pornstar.
Dude 1- "Check out this Asa Akira video man look at her ass!"

Dude 2- "Nah man I'm in a pornogamous relationship with Shyla Stylez!"
