Could you be a little more specific? I mean, there a LOT of meanings for the word "man". Do you mean psychologically, physically, spiritually, chronologically? Let me ask you this. How old are you? If you're under 18, you probably want to be very badly and therefore claim to be. If you're under 21, you're anticipating your passage into manhood at that keg party you've been talking about for ages. If you're under 25, you probably figure you're there, but the responsibility is weighing heavily on your shoulders. If you're under 35, you sadly admit your age to yourself as you can see the maturity in your face and eyes, yet you wistfully recall your boyhood. If you're 50 or over, you know what it is to be a man, dealt with it as a man would, decided you like being a boy better, and went about reliving your childhood through your "identity crisis". How's that for an answer of sorts?
