Yesterday my friend was probing for the first time after being shown how to do from a breeder and watching numerous videos on youtube about how to do it. Everything was going ok as he was probing his male pastel but when he went to remove the probe, the hemipene came out with the probe. After a few seconds of being back in the the vent, the hemipene "let go" of the probe. Is this a normal thing? Or was something done incorrectly to cause this?
