I would see if you can find someone local to you who will teach you how to properly do it. If you don't know what you are doing you can easily injure your snake.
I want to pop my bp to see what sex it is but I'm little nerviest doing it. Any suggesting?
Try to find someone who can show you, in person, how to do it. If that's not possible, you can learn by watching videos on youtube. Just be careful and don't be too aggressive. It's not very hard to learn.
