My suggestion would initially to get to know him as a friend. Don't go rushing in headfirst, cause that's doomed from the beginning, with any relationship. get close to him, be buddies, hang out, do "guy stuff", and most importantly you have to see if he's homosexual or not. If not, then i'm afraid there's a low chance, but hey, if he is then there's not many other options.
Anyways, i wish you good luck. Remember to be brave about it and dont shy away from anything that might come up to you :]
