XtoysSilexD Fantasy Collection Diamond Butt Plug Medium Review
Editor's opinion
The SilexD Diamond Butt Plug Medium is a body-safe silicone plug with a soft outer layer over a firmer core and a suction base for hands-free wear. It suits someone who has already used a smaller plug and wants a fuller fit. At 4 cm across it is not a beginner's first choice, and the silicone body rules out silicone lubricant.
The SilexD Fantasy Collection Diamond Butt Plug sits in the middle of a three-size range, aimed at people who have moved past a starter plug and want something with more presence. Its selling point is the dual density SILEXPAN construction: a softer surface over a firmer inner core, meant to feel more lifelike than a single-hardness plug.
What a buyer needs to weigh here is straightforward. The 4 cm diameter is the key figure, the suction base decides how you can wear it, and the silicone material dictates how you lubricate and care for it. Those three facts tell you almost everything about whether this plug is the right one for you.
The good and the bad
What works
- Body-safe silicone that is simple to clean and reuse
- Dual density build gives a soft surface over a firmer core
- Tapered tip and narrow neck designed to sit securely once in
- Suction base allows hands-free wear or use as a stable stopper
- Part of a three-size range, so you can size up or down
What to be aware of
- At 4 cm diameter, too wide to be a first plug
- Silicone body means only water-based lubricant is safe
- Suction hold depends on a genuinely smooth, flat surface
- No vibration or extra function, purely a wearable plug
Buy it if
Someone who has comfortably used a small plug and wants a fuller, mid-sized step up, and who likes the idea of hands-free wear on a smooth surface.
Skip it if
Complete beginners, who should start with the small size in this range or another slim tapered plug. Anyone who prefers silicone lubricant will also need to switch to a water-based one or choose a different material.
Design And Materials
The plug is built from body-safe silicone with a SILEXPAN dual density filling and an inner hard core. In practice that layered construction means the outer surface gives a little while the centre keeps its shape, which is what the brand means by a realistic feel. Silicone is also non-porous, so it cleans up thoroughly and lasts well through regular use.
The shape follows the familiar plug profile: a tapered tip that eases entry, a fuller body at its widest point, then a narrower neck meant to hold it in place. The 4 cm maximum diameter is the number to focus on, as that is the width your body has to accommodate at the widest part.
Shape And Wear
At 9.3 cm long and 4 cm across, this is a middle-of-the-range size. It reads as a considered step up for anyone who has already used a smaller plug rather than a starting point. The tapered tip does the work of easing insertion, but the fuller body still asks for a degree of comfort and experience.
The suction base is the other defining feature. It lets you fix the plug to a smooth, flat, non-porous surface for hands-free use, and doubles as a stopper that keeps the plug secure. Worth knowing: suction bases only grip properly on smooth surfaces such as tile or glass, so textured or porous ones will not hold.
Care And Cleaning
Silicone is one of the easier materials to look after. Wash the plug with warm water and a suitable toy cleaner, dry it fully, then store it somewhere clean and dust-free away from other silicone items.
The one firm rule is lubricant. Because the plug is silicone, use only a water-based lubricant with it. Silicone-based lubricants can gradually degrade a silicone surface, so keep them well apart. For anal use a generous amount of water-based lubricant is essential and worth reapplying, as the body does not self-lubricate.
How It Compares
Against a plain single-hardness silicone plug, the dual density build is the point of difference, offering a softer outer feel while the firm core keeps the shape stable. Whether that justifies choosing it over a simpler plug comes down to how much you value that lifelike quality.
Compared with vibrating or weighted plugs, this is a purely wearable, no-frills design. If you want stimulation beyond the sensation of fullness, look at a vibrating model instead. If steady, hands-free wear is what you are after, the suction base delivers exactly that.
The bottom line
The SilexD Diamond Butt Plug Medium is a well-specified, easy-to-clean silicone plug for someone ready to move up from a smaller size. Buy it if a 4 cm diameter suits your experience and you are happy to stick to water-based lubricant; if you are new to plugs, start with the small size in this range instead.
Frequently asked questions
Is this a good first butt plug?
Not really. At 4 cm in diameter it sits in the middle of the range and is better suited to someone who has already used a smaller plug. Beginners should start with the small size in this collection or another slim tapered plug and work up gradually.
What lubricant should I use with it?
Only a water-based lubricant. The plug is made from silicone, and silicone-based lubricants can degrade a silicone surface over time. For comfortable anal use, apply plenty and reapply as needed.
How does the suction base work?
The base sticks to a smooth, flat, non-porous surface such as tile or glass, allowing hands-free wear. It will not grip textured or porous surfaces. The same base also acts as a secure stopper during ordinary use.
How do I clean and store it?
Wash it with warm water and a suitable toy cleaner, then let it dry completely. Store it somewhere clean and dust-free, ideally kept apart from other silicone items.
What does dual density mean here?
It refers to the SILEXPAN construction, which pairs a softer outer surface with a firmer inner core. The soft layer gives some flex and a more lifelike feel, while the firm centre helps the plug keep its shape.
