OK. Is this a studied phenomenon? It just feels normal to me, but my girlfriend is having much stronger reactions to it, like she's pleasuring herself. It's weird. (She has playfully used the term "ear orgasm"). Maybe there's a bundle of nerve ending beneath there.
On my side if I touch a specific spot in the left ear it makes me cough for some reason.
I've got the same ear cough phenomenon. It's like my brain lost track of where it left all it's nerves, and when it gets a signal from one it lost track of it just does it's best. For some reason it's decided ear ~= throat.
Selfies are good at communicating emotion and context. It's a lot easier than trying to write down where you are, what's happening, and how you feel about it.
