I go to Dollar Tree & in the school supply section for $1 they have available two plastic test tubes (about the circumference of a quarter) with screw caps & a little tray to hold them upright.
As one adds loads to the plastic test tube, one can observe layers of frozen semen.
when it’s time to recycle, one could just thaw it completely or I just usually roll the tube in my hands to warm the plastic which in turn melts the frozen load which is in contact with the inner test tube wall. It’s not long before the cylinder of frozen semen disengages from the test tube wall and slides out of the tube.
at this point, depending on quantity on hand and piggy-ness of recipient, the whole cylinder can be inserted like one gigantic suppository. I usually corn cob the hole with the frozen cylinder. This allows the cum catcher to get a sample of every deposit made. It can melt rapidly while pushing it in & out of the hole. Once adequately cum sloppy & wet, place what r3mains of the frozen semen cylinder back into the plastic test tube, screw cap on, then place back into freezer.
