Photo's and exact "how to" of popping babies?

I have recently taken in 46 hatchlings... well, about a week ago.
I would really like to learn how to sex them. I came across a few sites that show how to pop, but... either all of the ones I've been trying to pop are females... which I have high doubts about... or I'm just not doing it right.

I read that it's real simple... all I have to do is bend the tail back a little, and roll my thumb a little above the opening gently but firmly. On one of the snakes, clear stuff came out of it's opening. Well, it's not working. I've even seen some pictures on a website... but they don't help at all.

I've tried probing; I bought the $20 probing set, and I do it gently, but it keeps going down very far and I'm afriad I'm hurting them. I don't want to hurt them.

Does anyone have any step-by-step clear pictures/instructions on popping?

This is as close as I've seen. Both of these pages have pictures, maybe they'll be of some help anyway.

Scroll down on both pages to fine the popping information.

With popping, it really helps to have somebody demonstrate it for you. The first bunch of times you it it will feel a bit awkward, but the more you do it, the easier it is (and the less you worry about hurting the snake). During my hiatus, I had no reason to pop anything and was quite out of practice when started getting babies last year. I had no problem popping the JC/Ds, but couldn't get the Dumerils boas to save myself. I did a bulk trade of the baby CY spotteds, so I never even bothered with them. With a little luck, I'll get it down again this year (if it doesn't come pretty easily, I'll load a bunch up and head over to a friend's place)

I wonder if you could find a local herp society or non-evil petstore that could help you with learning how to probe? I would definately try to find a live person in your area who might know how to help. good luck, sounds like you have some work to do!

in years past i was pretty good at probing boa's and pythons for gender . its been along time though so i'm not willing to try it yet . my boss at the petshop is going to go over it with me so that i can relearn it . i was never any good at poping an animal . i always was to afraid of hurting it .

All of my experience with popping has been with colubrids and boas.
I don't work with Ball Pythons, but I have always heard that they are notoriously difficult to sex by popping.

Popping in babies is more reliable than probing. I only work with balls, and I prefer to pop with babies. Adults are more difficult to pop, but it can be done.

It takes finesse...

today I learned how to do it! I wasn't applying enough pressure, and was doing it in the wrong places... heh.

Now, I came home and popped my first baby, but the hemipenes didn't pop out, just a ball of pink. If it's a female, will a ball of pink pop out? Or nothing at all?
