Sexing of my Shingleback Lizard (Tiliqua rugosa)

[sungazer]

Hello everyone,
Does anyone knows my shinglebacks' sex?
I'm not too confident they looks a pair so I need some opinion.
Thank you for reading.

For guessing sake I'll say they both look male but I'm not saying that with confidence. Trying to sex them visually is not the most reliable method.

I've encountered a few pairs of wild shinglebacks in my outback 4x4 safaris and adventures, and when I was working on projects and metallurgical plants in the outback as an engineering contractor.

My friend who has a 3 breeding pairs of shinglebacks , tells me males have a bigger, wider head than females and their tails are longer with a point to it.
Females tend to have a shorter, rounder tail.

So I think B = boy , C = girl.

A reptile / herp vet can evert the hemipenis to confirm.

C is a male, and B probably also male. Could you please show some side on head shots and I could be more accurate.

These are western shingles (rugosa rugosa) so unfortunately tail length or size has no relationship to sexing.

They both look male to me too, but I keep Aspera which are even harder to determine gender.
