I haven't really gotten into ASMR but there is something weirdly similar that's been on my radar long before it was a trend.
A decade ago I downloaded this MP3 that was supposed to give you a "hypnotic orgasm" without touching yourself, made by this female hypnotist named Isabella Valentine.
She whispers in your ear in this sensual voice but she doesn't do sound effects or anything, just hypnosis instructions (eg "your mind is slipping down a well" etc) though there is this binaural effect that I think is part of what hypnotizes you.
The crazy thing is, it somewhat works, while I've never actually managed to have a full orgasm while listening to it and sometimes it can be a total bust, when you're in the right mood and it works you feel intensely aroused and it actually feels like your penis is being stimulated in this really intense way, it's hard to fully explain but it'll shock the hell out of you.
The trouble is she drags it out way too long, it's about a 30 minute long MP3 in 3 stages, first she simply tries to put you in a trance, then she tries to arouse you and then actually stimulate you, but just when you feel ready to climax it she then "teases" you and drags it out, this is supposed to enhance it but only has the effect of deflating it like a balloon, when this is happening your body wants to tense up (she herself says this) but I always have to relax before the end in which it's then over, if it was a good 10 minutes shorter it might actually work, but she has to pull the stupid dominatrix shit at the end and ruin it.
It's still pretty awesome though and your results may vary, not sure how you can find this now but just Google "Isabella Valentine Jackpot No Hands"
Is ASMR something like that?
