When your eyes have been adjusted to the dark, and someone flips on the light. It’s not a physical pain so much as it is my occipital lobes screaming in agony. Only my eyes can hear it.
I hate the little spark of static electricity jumping from metal things to my fingers. I hate it. I guess it’s silly to get mad at electrons, but I have done so.
Also, I hate walking into spider webs, which seems to happen all the time. The little stringy things are hard to get rid of, and I hate when I don’t quite get one off and then I take off my glasses and I can feel it all over my head.
A tongue in my ear. Gah! Don’t do that!
Kinda worried now that I’m really weird since nobody mentioned mine, but -
touching sheets of paper with wet hands. ick! I’m ok with paper towels and napkins, but book pages or printer size pages I can’t do it 
I despise the sensation of someone whispering into my ear. It drives me insane. The warm, moist air from their breath and the sounds of the hushed voice… Arghh!!
This bothers me just writing about it, but…when you are trying to erase with a pencil or erasable pen and the eraser is gone so just end up rubbing that metal bit on the paper…
eeyuck. I’m gone.
Putting your lips on a peach that hasn’t been properly debrided of every last trace of fuzz – the tactile equivalent of nails on a chalkboard.
Worse: Those little planky wooden “spoons” that come with those little single-serving tubs of ice cream you used to get from the ice-cream man. God help you if you accidentally lick off the required buffer of ice cream and your tongue comes into contact with it. shudder
I am so glad I am not the only person squicked out by wood in their mouth. 
Fabric against my tongue. This includes that cotton stuff they use at the dentist. Gives me chills and repulses me.
You reminded me of another one. I have on occasion held a hangar in my teeth while I hung something, or tried to, but the plastic feeling makes me want to throw up. (No jokes, now.) It’s only with hangars; it’s always with hangars.
Handling wet yarn. Transferring a freshly washed afghan or sweater from washer to dryer = Bleaurghhhh.
Oddly enough, fingernails on a chalkboard doesn’t bother me, but wet yarn gives me the equivalent feeling.
Sweat on your skin (when it is 90F and 99& hmidity).
That odd felling when your testes recharge.
Styrofoam.
AAAAAAAAAAAAAAAAAAHHHHHHHHHHHHHHHHHHHHHHHHHHHH MAKE IT STOP
wet socks
dry hands
feeling too full after a heavy meal
When your feet get wet, in a dirty environment (like wet concrete ) and they dry and get like a film feeling it
The feeling of water from a spray bottle going anywhere but your hair.
the way it feels after a nail has been broken.
