i'm thinking male as well, but the lighting is bad on the underside of the legs. There are two things to look for, the femoral pores on the insides of the legs or the two hemipenal bulges on the base of the tail to determine if it is a male.
When taking a picture to try and have people identify the sex of the dragon a tip would be to darken the picture some, the white of the dragon on it's underside can have an adverse effect making the bumps hard to see.
I made a short picture guide to help this guy see if it helps you. viewtopic.php?f=1&t=136754
