Sexing?

[Ryder5406]

I know you've guys have seen hundreds of these threads but it always helps to have a second opinion. I have 3 leopard geckos. 2 of them are around the same age and weigh as best I can get with my scale about 60-70 gms. The third one is younger and is around 45-50 gms. The first two the older ones we're suppose to be a breeding pair.
The last one I bought was because I felt after stuff I'd read that they were actually females. So I bought the third one which is suppose to be a male. I've got pictures so can you guys help. First two are the older ones and the third is the younger one.

It's hard to tell for sure from the pictures, but the top two look female and the last possibly male. I feel like I see bulges, not sure about pores. It would help to have a closer picture.

I agree based on those pics the first two look female and the last one appears to be male. I see bulges but the pores aren't readily visible yet.

in keeping with complete disclosure the supposed male appears to have dropped his tail recently. Recent as I really don't know how fast they grow back but it's smooth underneath unlike the other two. It does't have the pronounced folds or scoots, whatever you call them, like the others. Would this slow his maturing into adult hood?
