How to Use the Stirrup C-Ring
Slide the 35mm ring over the base of the shaft before arousal begins. Gently pull the scrotum through the stirrup opening so the loop rests comfortably beneath the testes. Ensure the ring sits flush against the body and adjust for a secure, even fit. Apply a small amount of water-based lubricant if needed. Remove immediately if any discomfort occurs. This cock and ball sling can be worn during foreplay and intercourse.

Frequently Asked Questions
Q: Will the 35mm ring fit all shaft sizes?
A: The ring has a light stretch to accommodate a range of girths, but it is designed for average to slightly above-average sizes. If you prefer a looser fit, apply lubricant. For measurements outside the typical range, consult the sizing guide before purchase.
Q: Can the cock and ball sling be worn during vigorous activity?
A: Yes, the stirrup base holds the testes securely, making it suitable for active use. Adjust the fit before beginning and check periodically to ensure continued comfort.
Q: Is the silicone body-safe?
A: Absolutely. Tantus uses phthalate-free, hypoallergenic silicone that is non-porous and safe for intimate contact. Clean thoroughly with warm water and soap or toy cleaner.
Q: How do I prevent the ring from slipping?
A: The stirrup design naturally anchors the ring by cradling the scrotum. For best results, wear the ring as low on the shaft as comfortable and ensure the ball sling is positioned snugly behind the testes.
