I just had to Google asmr vids.
It's the very opposite of fapping material; in fact pretty girls are something of a distraction. But the world is kind of split into those who know the sensations such experiences can generate, and those who are thoroughly puzzled.
For some reason, some of us (many of us?) experience deeply relaxing, tingly sensations in the head during such things as hair cuts, massages, or a number of other weird and wonderful triggers. ASMR vids can be a trigger, but they're no substitute for the real thing. I don't get it as much as I used to, but it's like a kind of 'fizzing', tingly feeling that ripples around my scalp in a deeply soporific and relaxing way. It is absolutely exquisite while it lasts.
I miss my hair a lot, even after many years of increasing baldness. But I miss my trips to the hairdresser or barber even more. If I won the lottery I wouldn't buy a Ferrari, I'd buy a live-in masseur!
The only time I've ever heard anyone describing anything similar was when watching a documentary on drug taking. I've never taken anything more illicit than dandelion & burdock pop myself, but I think there's something dopamine related going on here and at it's best the sensations are far, far better than sex.
They last longer anyway.
Anyway, while I'm here... some folk are just bad at sleeping. I've never had the knack myself, but one technique which I've had more success with than most is listing animals (or names or plants or computer parts or whatever) working through the alphabet from A to Z. It requires just enough effort to occupy the mind, but isn't taxing enough to keep you awake. Ambient noise of stuff like streams or rain on tin roofs work quite well for me too sometimes.
