I'm not seeing male.
Your picture isn't the best for determining sex.
Those two lumps everyone is seeing, both sexes have two lumps there. It's the two lumps at the base of the tail that determine if its a male, not lumps at the vent. I don't see two lumps at the base of the tail. But, it could be just the picture.
Try to copy how the picture is in the how to sex your dragon article on this site.
