You can tell by the jugular scutes its female . Not only that if it was a boy it would of let you know by humping everything . After a year a male would start flashing his junk . If your asking at five years old than you can rest assured its female.
I'm just going off from what I've seen with my little males . Harry was about the same age as this guy when I got him . He humped everything . Dozer I was thinking female but he started humping things at about a year and a half old .Not all males have large gular scutes, and not all males do all that humping and flashing. I've seen quite a few that never flashed or humped anything. Especially at a young age.
