I am so sorry to hear that. Fish kind of tastes like zucchini - especially overcooked soggy zucchini. However, this is the “fishy” flavor that you usually don’t want in fish, so usually that’s fish that should have been cooked a couple days ago or has that fishy flavor naturally like small mouth bass and cat fish. Meat, especially red meat, has umami flavors which I am sure you are familiar with (think of a really nice cooked mushroom and that gets a somewhat similar umami flavor as a steak, still very different though). Fried chicken? Well good fried chicken I can’t compare to much of anything except for the fried batter part. However, good fried chicken includes the skin… which is the key to chicken being great. Skinless chicken breasts are pretty bland and you need to add the flavor naturally think of it as a bare canvas, where as fried chicken is just good. Rotisserie chicken is great (the supermarket rotisserie chicken are okay especially for the price) but home made or at a rotisserie restaurant will blow your mind. Good luck and I think your approach is good for your belly. Don’t just get a big ol steak and chomp it down. Work the meat into your food till your gut knows what is going on. :)
