I was overjoyed to find out there's an actual name and community attached to this phenomenon. I also think it overlaps with a portion of my robot fetish, and this might cross over with others here who haven't explored this possibility.
I think the biggest indicator around here may be if you enjoy watching people tinker with mechanical things. By "enjoy" I mean a physical reaction (relaxation, or tingles in your head, maybe mild euphoria, etc.). If watching people tinker can put you in a kind of mild semi-trance, then you may be experiencing ASMR.
The best way to describe it is the pleasurable inverse of most people's reaction to the sound of scratching a blackboard. Just so you know, I hate that sound too, and for the same reason -- but some other sounds are just as pleasurable for me as that is painful. For instance, I get pleasurable shivers when listening to whispers spoken directly into my ear (via audio file or IRL). I also get a sustained mild euphoria from being examined by an ophthalmologist, or when I get a haircut. I didn't realize until recently that most people don't have an intense reaction to electric razors buzzing at the back of their neck.
The feeling is not actually sexual. The best analogy is a massage. Given context and intent, it can become sexual, but is really just a sensual experience. Here is a kind of bridge video that may make this sort of thing clear for those into transformation: Being repaired.
And possibly for the rest of you: Tape recorder repair.
I hope this led to self-discovery for somebody here...
