Chastity and orgasm denial discussion

I’m attempting to keep calm while I enjoy some solitary afternoon play, teasing myself. Being locked up for a few hours has left my scrotum quite enlarged and puffy. I’ve popped the cage off and pushed my penis back through the rear opening, yet the swelling in my testicles is so severe that removing the base ring proves difficult. I applied a bag of frozen vegetables to help bring down the puffiness; at least now it seems possible to slip the ring free. Does anyone have suggestions?
