Yes, he is most certainly a male, as his spurs are clearly visible now. In the past few weeks I have noticed some features that can clearly be seen now...like his fingers...for some reason i thought this was funny. His legs have become much more solid looking and not so skinny now, his spikes have become much larger as well. Overall he is much more beefy than he was when I first brought him home. Im quite positive he was very young, as he looked more like a lizard than a cham for the first couple weeks!
