I know this is a couple years too late but i found this post while looking up ‘ground pork tastes weird’ and thought you might still appreciate an answer. This is what I found:

“Boar taint is the offensive odor or taste that can be evident during the cooking or eating of pork or pork products derived from non-castrated male pigs once they reach puberty. Boar taint is found in around 20% of entire male finishing pigs.”

Apparently some people are more sensitive to it than others. “Studies show that about 75% of consumers are sensitive to boar taint”
