How to let a very shy guy know you're interested?

Anonymous
Hi guys!
(Sorry for the long post.) I've had a crush on a guy for some 15 years, since I first met him at age 12. We were in our church youth group, but I was very shy and he never spoke to me. Over the years, he's only had one brief relationship (for about half a year) and I've been told that he is extremely introverted. Also, I'm friends with his parents, but he and I have never said anything more than hi.
I guess I want to move on and settle down, and finally learn if he could be interested in me at all. A couple months ago I contacted him over Facebook (oh, we're Facebook friends), and used some holiday as an excuse to ask him how he was doing. I found out that he's interested in Japan, and visited the country twice. So I asked him questions about his travels. I thought he'd get the hint after a couple weeks of me asking questions. But he always wrote me back quickly, with detailed messages -- but never asked anything about me (not even 'how are you?').
For Christmas I sent him a message, saying thanks and that I'd be interested in chatting with him more about his travels over tea or coffee. (Can I be any more obvious?) He wrote back that he was happy to help and didn't mind sharing about his trips. He said that he had some pictures and advice if I wanted to visit that part of the world.
What to do? Explicitly tell him that I'm interested in HIM, not as much in Japan? (Though keep in mind we're both introverts, and I think he's really shy. He never talks to anyone on the rare occasion he comes to church -- he just scoots out the door. Over the years I always felt that I gave him huge signs that I was interested -- I did all the things shy girls do.)
Anyway, guys, what do you think?
