FREQUENTLY ASKED QUESTIONS
FREQUENTLY ASKED QUESTIONS
Q: How do I decide which size in the 3-piece C-ring set to use first?
A: Start with the medium ring. If it feels too tight or too loose, switch to the large or small respectively. Never use a ring that causes pain, numbness, or discoloration.
Q: Can the Biird Riin rings be worn with a condom?
A: Yes. Place the condom on first, then stretch the ring over the base. This keeps both devices properly positioned.
Q: How long can I safely wear a silicone penis ring?
A: It’s recommended to wear a ring for no longer than 20-30 minutes at a time. Remove it immediately if you experience discomfort.
