P vanwaerebeki male genital issues?

[scumdogg]

Hi friends, I had my largest P vanwaerebeki male out for a walk around my hand today and he started doing a weird thing with his butt, I just got him a few days ago. His whole abdomen kind of looked a bit like it was straining, and his genital area would open and I think he was just barely pushing his reproductive organ out? It was very pale and looked really squishy, at the time I did have him out with another male from a different colony.  I only have video of the straining motion, he hasn’t opened his genital area again.
