Oxballs Steel Cum Thru Penis Plug with Ring is a stainless steel urethral insert measuring 4.5 inches long with 0.75-inch diameter, featuring a hollow center channel for fluid passage and a stabilizing base ring. The non-porous metal construction conducts temperature naturally while remaining hypoallergenic. It suits people seeking intense urethral stimulation with secure retention and premium build quality.
The Oxballs Steel Cum Thru Penis Plug with Ring functions through direct urethral insertion, with the hollow center channel allowing fluid passage during arousal or climax. The weighted stainless steel body transmits subtle movement and pressure sensations along the urethra, while the base ring sits securely at the glans to prevent slipping during use. Temperature conductivity means the plug can be warmed or cooled before insertion for heightened sensation contrast.
Stainless steel construction provides durability and non-porous hygiene that silicone cannot match. The seamless, polished surface resists bacterial colonization and maintains its finish through repeated cleaning cycles.

| Diameter | 0.75 inches |

Pairing the Oxballs Steel Cum Thru Penis Plug with external penile stimulation—such as hand stroking or a masturbator—creates layered sensation that combines internal urethral awareness with external pleasure. Many find that the hollow channel intensifies sensation during climax by allowing fluid passage while the ring maintains constant pressure. Using bondage harnesses can add hands-free security if extended wear is desired.
After each use, clean the plug thoroughly under warm running water with mild, fragrance-free soap. Pay special attention to the hollow center channel, using a soft brush or cloth to ensure complete cleaning inside and out. Dry completely with a lint-free cloth before storing in the provided pouch. Stainless steel resists corrosion, but thorough drying prevents water spotting and maintains the polished finish.
Stainless steel construction ensures non-porous, hypoallergenic safety suitable for sensitive urethral tissue. The seamless, polished surface resists bacterial growth and simplifies cleaning compared to textured materials. Its durability means the plug maintains structural integrity through years of use without degradation, while temperature conductivity enables sensory exploration without specialized equipment.
This plug suits people with penises seeking intense, focused urethral stimulation combined with secure retention during extended sessions. Those interested in temperature play appreciate the metal's natural heat and cold conductivity. Experience level varies—some users are advanced in urethral exploration, while others are curious beginners seeking a premium entry point into this sensation type.
For people who have experienced hollow silicone plugs that collapse under pressure or solid plugs that block sensation, discovering that stainless steel can be both hollow and rigid transforms what urethral play feels like. The hollow center channel creates a unique sensation pathway unavailable with solid designs—fluid passage during climax intensifies awareness in ways that blocking sensations cannot replicate. For those frustrated by plugs that migrate or slip during movement, the stabilizing base ring provides security that allows focus on pleasure rather than constant repositioning. The metal's weight and temperature conductivity add sensory dimensions that plastic alternatives cannot deliver, shifting urethral exploration from functional insertion into genuinely pleasurable sensation.
Our independent testers evaluated insertion ease, retention stability, hollow channel functionality, and temperature conductivity. The tapered tip inserted smoothly with adequate lubrication, while the base ring remained securely positioned throughout extended wear without migration or discomfort.
Testers reported that the hollow channel noticeably intensified sensation during climax as fluid passed through the center, and that warming the plug beforehand created distinct sensory contrast compared to room-temperature insertion. Individual results may vary based on anatomy, sensitivity, and usage.

|---|---|---|---|
| Oxballs Steel Cum Thru Penis Plug with Ring | Hollow center channel with temperature-conductive stainless steel | Only design combining fluid passage with metal construction and base ring | Hollow urethral sensation plus secure retention and temperature play |
| Solid Stainless Steel Urethral Plugs | Maximum pressure and density without hollow center | Blocks fluid passage; provides solid internal pressure instead | Dense, blocking sensation without fluid awareness |
| Silicone Hollow Urethral Plugs | Softer material with flexibility during insertion | Less durable; cannot conduct temperature; may collapse under pressure | Gentler insertion with flexible material |
| Urethral Sound Sets | Progressive sizing for gradual exploration and sensation variation | Multiple tools instead of single fixed plug; requires more technique | Graduated urethral exploration with different diameters |
