Great thread! Fun to see I'm not totally abnormal, anyway.
Bananas, tuna, and eggs (especially hard-boiled) are things I would only eat after days of starving. Although, oddly I will eat souffle that I make myself and egg drop soup. Quiche is on the edge-the texture bothers me especially if it's room temp or cooler. I can taste banana in anything, even bread or a smoothie. Ugh, no. I cried in front of my elementary school because they served tuna sandwiches unexpectedly one day for lunch. As a child, I would basically have to leave the room if any of these things were being eaten by others. I will move a trash can with a banana peel to another room if possible.
Other things I've worked on and made progress with, such as: spicy (picante) food; beans (pinto are a no but black beans are ok); beets (taste like dirt but can handle it ok); cilantro (can at least pick it out rather than abandoning entire dish but yeah still tastes soapy).
Totally understand a bunch of the other aversions, like different foods not touching on the plate, and people reaching into chip/popcorn containers. I will only share those with DH.
