I'm bi-curious and in love with my best guy friend. what do I do?

I'm' bi-curios and I'm in love with my guy best friend. we treat each other us brothers and all but I don't have the courage to tell him my feelings. We get really close to each other we even wrestle and tickle each other all the time. We would also hold hands together while walking and he won't mind if other people see us together.

What I need right now is an answer, should I tell him my true feelings in case he reciprocates? Nothing would make me happier than to just be with him, I don't care about the future as long as he is in it. Or shall I try and get over it? I've tried before on several occasions but it's impossible since he's my best friend, and completely ousting him from my life would be even more painful since there would be no point to getting up in the morning if I knew I wouldn't see him. What should I do?
