How you addressed this is nice. I can't say there's no beauty and joy in exploring new places and learning of them and their people, culture and so. It's such a wonderful experience. But the consideration about insecurity is a very valid concern that could cripple such desire. And just for the fun of it in such a situation doesn't seem okay enough. Life matters more than the experience, or fun even.
