The XR 3-Prong Adjustable Anal Speculum, sold under XR's Master Series line, is a slim steel instrument with three prongs that spread apart once inside. It's an anal speculum for medical-play fans and couples into exam scenes, voyeur play or gradual stretching, where the thrill is in the slow, controlled opening and the view it gives.
Two-bladed specula open in one direction, like a duck's bill. Three prongs spread outward in three directions at once, so the opening is rounder and the pressure is shared around the rim rather than pushing on two sides. Closed, the probe is about 3.5 inches long and roughly ¾ inch across, slimmer than many beginner butt plugs, so insertion itself is usually easy. Opened fully, the prong tips spread to a maximum of 2.5 inches apart. Most people never need anywhere near the full spread.
Warm up first with fingers or a small toy, and use plenty of lube on the closed prongs. Insert slowly, let the muscles settle for a minute, then open the prongs in small steps, pausing after each one. The receiving partner should guide every adjustment, and you should close the prongs fully before removing it; never pull it out while open. Stop at sharp pain. A small flashlight or phone light helps if the view is part of the scene.
It suits people who enjoy the visual and psychological side of anal play, being examined, displayed or slowly opened, more than the feeling of fullness. If what you really want is a sustained stretch you can wear, a graduated set of butt plugs is easier and more forgiving. It also isn't a first-ever anal toy: if you've never had anything inserted, spend a few sessions with fingers and a small plug first. Because the prongs are rigid metal, wait until any soreness or irritation has fully settled before trying it.
Medical play is as much about atmosphere as equipment. Gloves, a towel-covered surface and a calm, clinical tone of voice all add to the role-play, and the cold steel itself is part of the sensation. If you'd prefer it warm, run it under warm water for a minute first; metal also holds cold well if you rest it in cool water. Agree on a safe word and talk through limits before you start.
Steel is non-porous and works with water-based, silicone and oil-based lubes. A thicker water-based anal lube holds up well during slow play. Wash the speculum in warm soapy water straight after use, work a soft brush around the hinge and between the prongs, rinse, and dry it completely. Store it closed, in a pouch, away from softer toys that could be scratched by the metal. Before each session, run a fingertip along the prongs and hinge to check for burrs or scratches, and close the prongs slowly so skin doesn't get caught between them.

Helpful answers about XR 3-Prong Adjustable Anal Speculum.
The closed probe is slim, about ¾ inch, so insertion is manageable. Opening it is the advanced part. Beginners should spread the prongs only slightly, go slowly and let the receiving partner call every adjustment.
The prong tips spread to a maximum of about 2.5 inches apart. That's a big stretch, so treat it as an upper limit rather than a target, and close it fully before removing it.
Any type: water-based, silicone or oil-based lubes are all fine on steel. For slow anal play, a thick gel from our anal lubes collection stays put longer than a thin liquid.
Yes. Steel takes on temperature quickly. Hold it under warm tap water for a minute, or rest it in cool water, then dry it and test it on your inner wrist before use. Avoid boiling water, ice or the freezer, which can make it uncomfortably hot or cold.
The Graves speculum has two blades that open like a bill and can be used vaginally or anally. This three-prong version spreads in three directions, giving a rounder opening, and is designed for anal use.
Open the prongs fully outside the body, then scrub the inner faces and the hinge with a soft brush and warm soapy water. Rinse, dry with a lint-free cloth and leave it open to air-dry before storing.
It can be when you go slowly, use lots of lube and never force the opening. Stop at sharp pain or bleeding. Read our guide to safe BDSM for tips on consent and negotiating medical scenes.
