male or female

Ok the kittens are close to being old enough to leave the nest. Can anyone tell me how to tell the males from the females?

I know I had seen a thread on this before. A pictures was even sent but made me even more confused,as my babies were too little to tell still. Well they aren't anymore and there is a destinct difference in the kittens' privates. Can anyone help me to tell which is which.

those are a few sites, so you have a choice on which are better for u to see on the babies

Thank you,
After posting did a google search and got some good info and pictures also.

What color is mom and dad and the color of the kittens. If you have any torties/calicos they should be female - use it as a guide for the rest.
