Male. It is just large enough to start showing the secondary sexual characteristics. The gulars are starting to extend. The anal scutes are flaring out and starting to thicken. Can't see the tail, but it is tucked to the side and looks like it is getting long. Also from the angle it is not easy to see, but the shadows seem to indicate it is starting to get concave in the plastron. That actually accelerates if/when there is breeding/mounting activity.
