The foods we've consumed for years have once been new to us too, and the problem is one of being locked in our ways. You can get to know variety better if you try something different every once and a while, and choose the same stuff you really want.
There is no point in banging your head against a wall of bricks trying to develop a taste for something you don't like. You'll never know if you like anything, though, until you actually try it. This is especially true with respect to international cuisine. It may look different but it is eaten regularly by millions of people, so it can hardly be toxic. It's not going to be your death to take a leap of faith and try another food, so why not try something different once a week and surprise yourself with how much you enjoy it?
