I used to eat liverwurst sandwiches when I was a kid. I must not have had taste buds back then. I won't touch the stuff now. My oldest son also ate liverwurst sandwiches when he was little too, but like me, he wouldn't touch it with a 10 foot pole now. He's a very picky eater still, even in his 50's.
Tastes change ... hit my 60’s and now I like Stinky Cheese and Liverwurst (I like Hard Cheese mostly but a little bit of soft Stinky Cheese dipped on the end is now OK)
