Male or female? That is the question...

[stayAThomeGECKOmom]

Here are pics of my two leopard geckos. I'm pretty sure the first is a female but I'm not sure on the second. The first is 2 years old and the second was a recent +++++ purchase and we were told it was between 9-12 months old. I've searched the internet, watched different videos and read different forums and I still don't know 100% what I have. Can anyone tell me for sure please?

They both look female to me.

the second one is a little trickier, but I would still say female.
