It's a fact that some people have more taste buds than others. I can taste and smell things that my husband can't, even though I'm a smoker.
I love pork, but when we re-heat it, I can sometimes detect a "different" taste that one could describe as slightly gamey. The pork isn't spoiled...that's just the way it tastes. I've also noted that taste in bacon after it's been in the fridge a while. We have friends who slaughter their own pigs, and the bacon from their freezer alway seems to have that taste.
IMO, all raw meat has a certain odor, which varies depending on the kind of meat. Chicken can be really rank. This is when lemon juice is your friend. Just splash a little over the surface of the raw meat (the bottled stuff is fine for this), and the odor is gone, and you get a fresher, cleaner taste. That may help you with your pork, too. You might give it a try.
