You get hard. A few minutes later you're not — and you both noticed.For most men who lose an erection during sex, getting blood in was never the problem. Keeping it there is. Blood flows in normally, then drains back out before you're finished. The Sanelius Ring is a soft silicone erection ring worn at the base that slows that drainage, so the erection you already have is the one you keep.Targeted compression. Physics, not chemistry. No pill, no prescription, no forty-five minute wait — it goes on in about five seconds.When do you lose it?Most men can name the exact moment. Every one of them points to the same mechanism: When you put a condom on. The pause and the change in pressure are enough for blood to escape. At penetration. The shift from hand or mouth to a different kind of pressure. When you change position. Movement briefly drops the pressure holding everything in place. On round two. The second erection drains faster than the first. The second stimulation stops. You stay hard only while something is actively happening. If you recognised yourself in that list, the problem is mechanical — and a constriction ring is the mechanical answer to it.Choose your compression levelThe ring comes in three levels. They are the same shape in three internal diameters, so the difference you feel is how much drainage is slowed. Light — start here if this is your first erection ring. Enough to notice, gentle enough to forget you're wearing it. Firm — the level most men settle on after a few nights, once they know how it feels. Intense — the tightest. Not a starting point, and not for everyone. Not sure? Start with Light. You can move up; moving down is the uncomfortable direction.How to wear it safelyRoll it on at the base once you're erect, or before — either works. Then: Thirty minutes maximum, every time. The compression level does not change this limit. Take it off immediately if you feel numbness, pins and needles, real pain, or if the skin turns dusky or cold. Never sleep in it. Leave at least an hour before wearing it again. Speak to a doctor first if you take anticoagulants, have a bleeding or clotting disorder, sickle cell trait or disease, a penile implant, reduced genital sensation, or have had recent penile or prostate surgery. The materialHypoallergenic, body-safe medical-grade silicone. Non-porous, so it washes properly with warm water and mild soap and dries in minutes. The three-point shape holds its position instead of rolling, which is the usual reason a tension ring stops working halfway through.Try it for 30 daysIf it does not do what you bought it for, email us your order number within 30 days and we refund you in full.
