Thanks for the cola experiment.
Maybe with a balloon filled half with coke and the other half with air. Then you pull the balloon over the penis so that it is completely in the balloon but does not touch the cola yet. Provide a zip tie to have an extra seal afterwards, but make sure enough blood can still flow into the penis.
While standing, tie yourself with a spreader bar at your ankles and then release the air from the balloon, tighten the zip lightly, shake the balloon for a moment and then tie the free hand.
