Well finally I got a name for it, I was experiencing it when I was a child, especially strong when some neighborhood girl was doing some girly tests with me with her fingers crossed or something. Totally felt like I was in a trance, and a pleasent feeling on the back of my neck and head. Also a strong one was when I was watching flight attendants show the safety precautions on every plane, weird gestures with their hands showing belt and emergency exists, but only from beautiful women (not men). Also when I watched these flight attendants on youtube, very strong sensation. You should include this type of video. I think it is a rather intimate feeling not meant to be shared with many people (anonymous people on the internet don't count) :D
Having previously practiced yoga and meditation for over 10 years, I can induce ASMR at will, or "bliss", as it's called in the spiritual community. It's often part of the very first steps on a spiritual journey, though no requirement. These videos didn't induce ASMR in me though, so maybe it's a different sensation than "bliss", or different triggers.
The study is still ongoing, and results have not yet been published. But for his part, Richard has been developing a theory of what ASMR is and why it exists. His theory isn't exactly scientific, but it is beautiful: He notes that the quality that underlies almost all ASMR videos is what’s been called a “tranquil, womb-like intimacy.” That is, ASMRtists speak softly into the ears of headphone-wearing viewers, gently coaxing them to sleep by way of assiduous personal attention, comforting words, smiles and simulated stroking. At its most essential level, Richard believes, all the intimacy channeled through towel foldings and whispered affection is about triggering the felt experience of being loved.
