blue tongues

Question

Answer
Alas, sexing blue-tongued skinks is challenging, and I can't do it for you online--nor can anyone else!

This site has excellent and highly detailed care information, breeding information, and information on sexing:

As you can see, sexing blue-tongued skinks often comes down to brumating them, and then putting them together and seeing whether they fight or breed!

Be sure that both animals are fully mature, have great body weight and health, and have gone through a proper brumation period, before pairing them.  Proper nutrition for breeding animals is absolutely crucial.
