Look like 2 females to me

 

[NickGeee]

How old are they?

 

[Planky]

The supposed male is around 1.5-2 years and the females 3

Also if anyone has pictures of there geckos feel free to post then so I can learn the difference between sexs

 

[geckoman1985]

Both girls. You need a male

 

[Planky]

So are knobbies like spiny tails and have a more visible ball sack ?

 

[NickGeee]

All geckos have very big balls.
I'm tryingto upload pic but having trouble

 

[mummabear]

I would say 2 females.

 

[NickGeee]

Heeeere we go!
This is an 18 month old male.

 

[saintanger]

yeah they are both girls your lucky, you only need to find a 1 male now.

 

[Planky]

And yes, 2 females. The easiest way to tell is by looking top down at the base of the tail. The protruding two white dots are called hemipenal buldges (seen right in image below), the females do not have this buldge. They do have a white dot in the same position but it's no where near as large as the male's white dots. The hardest part about sexing this way is that you need to make sure the gecko is of mature size for this to work. Otherwise even male geckos will have small white dots if they haven't matured.
