I don't know why the only fish I like is sushi. I went to Hawaii and they have this stuff called poki, which I'd never heard of, but it's raw tuna marinated in different ways over rice, and it was the most delicious thing I've had.
I used to think that I'm extremely finicky, but now that I'm trying to think of all the foods that disgust me, I'm drawing a blank. Somehow, I thought there were more.
I'm with you on the tuna thing, the thought of that person eating it on the quad disgusts me. I can't stand even being around that sickening smell.
