Are you prepared to be rejected if he isn't gay or doesn't like gay people? Remember any time you make a decision like this you have to be ready for any outcome. 
And I really agree with joypulv in that you should appreciate having a close friend and maybe wait on taking it to the next level. If he knows you are gay and hasn't expressed the least bit of interest in having more than a friendship with you, that may be a signal that he isn't gay.
And remember something very important. Being gay is a small part of you. It isn't the only part of you. So don't define yourself as gay and gay only. You are a son, a student, a friend, a nice person, etc, etc, etc.
