Think about what stuff you like, and what stuff does he like. Then compare both lists, even if it's mentally. Search a theme in common, try doing that and later, try talking to him about themes you like and he doesn't know a lot about, explain to him everything and things should flow easily.
Try having deeper, meaningful conversations. Talk about things that make you wonder, talk about your beliefs, talk about what makes you passionate and happy! Finding someone who you can have meaningful conversations with is a wonderful thing! Leap into a journey of truly knowing each other by sharing what truly goes on in your minds. -Not everyone is open to it though, so don't be frustrated if he doesn't seem receptive... It takes time to open up, take off the mask and exposing your true self.
