Kink spiral 

An observed phenomenon where one must increasingly turn to hardcore pornograpgy in order to achieve arousal as they become decentcitized to vanilla pornograpgy.

Coined by a feminist author named Naomi Wolf (an 8/10 MILF might I add)

Mike: I watched porn 4 times today.
Tyson: dude, careful. You might descend down the kink spiral.
