Size & Fit Guide
Cock rings are all about girth, not length. Though the added pressure from the rings can help lengthen a little bit it is not the main function. So how do you choose the right size?
Snugger - Tighter Hold
Best for:
- Penis girth 4.25–5.25 in when erect (108–133 mm circumference)
- Slim to average girth
- Scrotum holds, and snug fits around the penis head
- Those who want a firmer, more “locked-in” feel
Inner opening height: 1.10 in (29 mm)
Snug - More Breathing Room
Best for:
- Penis girth 5.25–6.5 in when erect (133–165 mm circumference)
- Thicker shafts
- Longer wear and relaxed comfort
Inner opening height: 1.34 in (34 mm)
Fit Tip for Condom Use
If you plan to use Cerus primarily with a condom around the head, start with Snugger for a secure fit that helps keep everything in place without over-tightening.
Fit Tip For Sizing
If you’re between fits or new to cock rings, start with Snug. You can always size down to Snugger once you know your comfort zone.
The Benefits of Cerus
Comes with two tri-rings (Snug and Snugger) so you can dial in the fit that feels right for your body, comfort level, and the perfect pressure.
Helps hold blood at the base of the shaft, supporting firmer erections without feeling overly tight or cutting circulation off.
Designed to support stamina with steady, balanced pressure, so you can stay present and last longer without losing all sensation.
Four Ways to Use It
The Cerus Tri-Ring is designed for flexible wear depending on your anatomy, comfort level, and desired sensation. Its tri-ring shape and stretchy silicone, it supports multiple positions including condom play.
Shaft Support
Worn around the base of the shaft to help maintain firmness and support blood retention during arousal.
Shaft + Testicles
Positioned around the shaft and behind the testicles for a more anchored, locked-in feel and increased intensity.
Testicle Focus
Worn around the testicles only for lighter pressure and heightened sensitivity without shaft compression.
With a Condom (Around the Head)
Worn just behind the head of the penis, over a condom, to help keep the condom securely in place and reduce slippage during use.
- The Snugger ring is best for this fit due to its tighter hold
- Always use water-based lubricant
- Adjust slowly to ensure comfort and proper circulation
