## Emma's take

Stays put, holds firm, lets you focus on everything else.

The Stirrup is Tantus's take on the classic cock and ball sling, built from firm-yet-yielding platinum silicone that stretches to fit, grips the shaft, and holds the testes in place through an open base designed specifically for that purpose. Reviewers note the 35mm inner diameter sits snug without pinching, and the nonporous silicone goes straight into the top rack when the session ends. Worth it for anyone who wants to stay harder longer without fussing with straps or closures. Less suited to those who prefer a fully adjustable or vibrating ring.

## Frequently asked questions

## What makes the Stirrup different from a standard cock ring?

Most cock rings sit around the shaft only. The Stirrup adds an open base that loops around the testicles, keeping them from drawing upward during arousal. The result is a firmer, fuller erection that holds longer than a shaft-only ring typically achieves.

## How do I put the Stirrup on correctly?

Slip the shaft ring on first when semi-erect, then guide the lower opening around the testicles one at a time. The silicone stretches enough to seat comfortably. If either step feels forced, a small amount of water-based lube on the ring eases the process.

## How long is it safe to wear the Stirrup during a session?

The general guideline for any constricting ring is 20 to 30 minutes of continuous wear. The Stirrup's soft silicone distributes pressure well, but always remove it if you notice numbness, discomfort, or any change in sensation.

## Can I use this ring with a partner who uses silicone-based lube?

Stick to water-based lube when using the Stirrup. Silicone-based lubricants can break down platinum silicone over time, degrading the surface and shortening the life of the ring.

## How do I clean the Stirrup after use?

The Stirrup is top-rack dishwasher-safe and bleachable, making cleanup straightforward. A 10% bleach rinse or a run through the dishwasher (no heated dry needed) fully sterilizes it for shared use. Rinse well before storing.
