This is what lifelong meat eaters experience, but I just can't comprehend. There is no meat that on its own is particularly tasty to me. Chicken, at its absolute best, tastes like a disappointing roast chestnut. What's worse is meat doesn't really marinade as well as everyone makes out, so often I'll be enjoying a dish but I keep chewing and realise I just like the sauce and then that fades and - yuck - you're left with meat.
Again, this is my very narrow experience as a vegetarian who lapsed well into adulthood and just didn't learn an appreciation of the savoury flavours involved. Objectively it's clearly people love the taste of meat.
Chicken is about the worst meat to eat on its own, especially if you are baking boneless skinless chicken breasts. Dark chicken meat has actual flavor, so thighs and drumsticks are probably your best bet.
If you want good meat with no extra flavoring I recommend good steak (like the $60+ steak you can get at a nice steakhouse). Pulled pork is also good, though it's usually somewhat flavored, doesn't necessarily need to be. Lamb prepared gyro style is pretty good. Pretty much any meat will taste better grilled than baked in an oven too.
