New Owner, Need help gender identifying

[Kylew2015]

Heyyy,
I am a newer leopard gecko owner. I recently purchased two geckos from a pet shop (yes I know that’s not he best idea but I wasn’t able to locate local breeders).
Upon purchasing them I wasn’t told the gender. Now I have done numerous research and looked it plenty of photos but I’m still having a hard time confirming since my geckos are so young.
One I’m fairly certain is female but the one I can’t tell is in the pictures I’ve attached.

I’m housing them in the same tank. And they don’t fight or seem to have any issues whatsoever.
If someone could please help me determine the gender I would sincerely appreciate it.

Sorry, not a clue. I incubated for males and females one summer (as opposed to lower temps for females) and spent a miserable few months peering at gecko bottoms with a magnifying glass. They may also be too young.
