It was revealed in Pornhub’s 2017 Year in Review that ASMR was one of the top trending searches of the year.
According to Wikipedia, Autonomous Sensory Meridian Response (ASMR) “is a term used for an experience characterised by a static-like or tingling sensation on the skin that typically begins on the scalp and moves down the back of the neck and upper spine” and that “it is most commonly triggered by specific acoustic or visual stimuli, and less commonly by intentional attention control.”
Perhaps it’s the “acoustic stimuli” and “intentional attention control” that leads to the natural relation between ASMR and JOI. Although JOI stands for Jerk Off Instructions, it’s not meant to be a tutorial video, but rather a type of vocal coaxing that will turn-on the listener and guide their masturbation towards orgasm.
