I have a for sure 100% female Iran Jaya blue tongue thats an 06. My other skink i have owned for about 6 years and i was told by my vet that it was a female from x rays. Here are two video's of them together. Judging by the way they act around eachother do you think my other iran jaya is a male or female? The female is the one doing all the tail wagging, shes ready to breed i just need to find a for sure male to get the job done.

This next video watch the darker one walk up to the female with its shoulders and back turned upwards. This makes me think that its just a territorial female.
