Conversation starters - Help !

Hey people, I'm 17 yet I have no experience in dating, but I met this guy and he actually suggested to hang out and I have no idea what to talk about, because when I'm around guys I'm interested in I know I'm silent and kinda gloomy, so any advice please help

p.s. he's like a perfect guy he's excellent in sports and academics and he does so many outside activities but none of them that I know much about !
