I have not got a photo, but i may be able to help you sex it.
Males have preanal pores thet are very easy to see, my males look almost like hairs! they are that long!
also adult males make the "gecko gecko" call
and they are huge! much bigger then the female. our male is 14 inches long and he as a huge head. He's about the same size as a female beardie! they are BIG geckos

but if you look in my photos in the gallerys you can see him from the front
