Because I am trying to figure out how to pop (aka I'm testing it out) on my adult "male" ball python. I've had him for a few years and I wanted a snake to test it on, knowing he is a male. Well I tried popping and got plugs (well that is what I assume they are) but I couldn't get his hemipenes to come out, which is what popping is supposed to do, showing that it's a male.

Could be that I'm doing it entirely wrong, or it could be that he's a she if shes can produce inch long white things (almost like icicles) in their tails. I'm not going to try and do it again tonight for fear of stressing the snake out or injuring it. I've been trying to watch the videos and figure it out from there and this isn't my first attempt at doing it (I've done it one other time a couple months back to the same results).
