I have a crush on a guy friend & he's the really smart, nice, & naive/innocent type. He told me that he's straight but has no experience with dating, relationships, etc. Is it worth liking him? Do I even have a chance?

I think you probably do have a chance. It's good that you're already friends, because relationships usually last longer if the people are friends first. You said that he's straight, but this is anonymous, so I'm assuming you're a girl. If not, then don't say anything because it might affect your friendship. As for the lack of experience, everyone has to start somewhere :) Good luck!
