I never much cared for fish, as the smell and taste both lead me to want to toss my cookies.
Crustaceans and mollusks have the same problem, to me, though I equally get bothered by their texture. Shrimp and clams are definitely a "no-no" for my dinner plans.
I decided I'd wait to the end of my post to cheer a tiny bit, as I'm a vegetarian, myself. I've only been a vegetarian for about 19 months now, though I did try to roll as a vegan for a good 3 or so months. I'm very strict about my diet, as I never counted pescatarians or other such groups as literal vegetarians... Anyhow, I do eat eggs, honey, and dairy.
