yeah, i was... when i was 18-19 years old. it ended badly, since i came out to him and afterward told him about my feelings about him... he still hates me after two and a half years and won't talk to me. so my advice is... if you cherish your friendship with him, keep your feelings to yourself and try to suppress it as much as possible until you don't have these feelings for him. i know its sounds difficult, but you will probably have to choose between a friendship or no friendship... i assume he's straight, since there wouldn't be as big of a problem if he was bi/gay and you wouldn't answer the question to begin with
