I have the Contender. Trying for long term chastity. I am having trouble where one testicle keeps slipping out of the base ring. Does anyone have any experience about how to fix this? Would it help me to increase the gap between the base ring and the cage. The cage part is snug. The base ring rides down on my shaft about 1.5 inches from my body.....my sense is that I need to increase the gap distance between the base ring and the cage so that the base ring is more up against my body. Maybe my thinking isn't correct as I'm not a great "engineer' in my strong suits.
Bring this to Mark. He’s a great engineer! I would go with a smaller diameter basering, or narrow the gap to prevent them slipping between the cage and base rings. Also an oval ring can reduce the distance between the bottom of the base ring and the bottom of the cage ring as well. Your balls can pull through the base-cage ring gap, and then through the base ring itself.
