Something kinky.
Those blue thingies on his dick are at high voltage: they’re used for recharging female p-morphs. And that white liquid substance is nano-grease: an important component of their bodies which does repair and maintenance. Females can’t produce it, so it’s males’ job to deliver it x)
P.S. They don’t have balls: that bulge is just a technical node. Actual nano-grease generator is hidden inside the body.
