Late to this thread, but by heck I've just had a revelation this very night.
I'd never heard of the term ASMR before - and looking at the Wikipedia entry its highly, er, 'disputed'. Not that wikipedia is any use as a first reference of course.
I've had this ... 'ability'? ...shall we call it? all my life. In fact I collect videos, audio recordings, and I jot notes that provide memory triggers of when this happens.
The sensation is always pleasurable - highly pleasurable in fact - and accompanied by a great sense of calm.
It has an 'arc', usually somewhere around 10 minutes, though in its most intense form it can last a bit longer - say 20 minutes tops.
Sorry for the Too Much Information but in the interests of information completeness - if I masturbate whilst under the influence of this sensation, the orgasm I experience is extremely intense and can almost cause a blackout. I'm male, and not used to such things
Also, it causes such muscle relaxation (I am guessing), that generally when the sensation wears off I have to rush to the toilet and void my bowels.
The trigger is usually voice, though I have noticed that, with me anyway, common factors that will trigger it are (and have more power in combination also):
* Low spoken voice (low volume but also soft tone)
* Hand gestures, especially slow
* Intimacy - as in if the speaker's focus appears to be directed specifically at me; this also works if the speaker is just good at conveying that impression, ie. a good public speaker/lecturer
* A European or Slavic foreign accent
On youtube I've been watching Jim Winter's Palm Reading videos, even though I think Cheiromancy is a load of bunkum (hardcore atheist, me, but he's such a nice guy and has such a voice). And today I discovered this woman, she seems to be deliberately aiming at this effect:

I'm very interested in this now. And additionally because I'm conducting Learning Systems research at the moment for a Masters thesis. And of course, because I'm an Aspie !
I would love to hear from other people with respect to this effect.
I can't believe its got a name, but I'm glad it does - it took me decades to discover 'Aspergers' after all
Ah, and a rather interesting thread on another site (ignore the serotonin guff):

Update:
Well I'll be! There are a *heap* of dedicated ASMR videos on youtube, just put the acronym into its search.
