What Are Dildos Made Of? A Guide to Materials and Realism
Two toys can share the same dimensions, the same shape and the same photo angle, and one will feel like skin while the other feels like a bicycle grip.
The difference is material. Not just which material, but how it was built — and the gap between the two ends of that range is far wider than anything you can tell from a product listing.
This covers what's actually on the market, which ones are safe to keep, and what separates a piece that genuinely feels real from one that only photographs well.
Quick answer: Platinum-cured silicone is the safest and most realistic option. It's non-porous, so it can be fully sterilised, and it holds warmth. TPE and TPR are softer and cheaper but porous. PVC and jelly are the ones to avoid.
=====================================================
Porous vs Non-Porous: The Thing That Matters Most
Before any brand name or price, there's one property that decides almost everything else.
Non-porous materials have a sealed surface. Nothing gets into them, which means they can be cleaned completely and sterilised properly. Silicone, glass, stainless steel and hard plastics are all non-porous.
Porous materials have microscopic openings across the surface. Bodily fluids and bacteria get in and cannot be fully removed, no matter how thoroughly you wash them. TPE, TPR, PVC, jelly rubber and latex are all porous to varying degrees.
This is why porosity comes first. A porous toy can't be shared safely, can't be properly sterilised, and has a limited lifespan before it should be replaced. A non-porous one can be boiled, cleaned with a dilute bleach solution, and kept for years.
It's also why the cheapest toys are cheap. Porous materials cost a fraction of what silicone does.
=====================================================
Every Material, Compared
Platinum-cured silicone
The best option in this category, and what any serious realistic dildo should be made from.
Non-porous, so it can be boiled or bleached. Chemically stable, so it doesn't leach anything. It holds body heat once warmed, which matters more for realism than most people expect. It can be moulded to extremely fine detail — skin texture, veining, the softness variation across a single piece.
The one limitation: silicone lubricant degrades it. Use water-based.
TPE and TPR
Thermoplastic elastomers. Very soft, very stretchy, considerably cheaper than silicone, and genuinely pleasant to touch.
But they're porous. They can't be sterilised, they absorb odour over time, and they degrade faster. They're also incompatible with both silicone and oil-based lubricants. TPE has a real place in the market at lower price points, but it's a material with an expiry date rather than one you keep.
PVC and jelly rubber
The soft, translucent, often brightly coloured toys with a distinct chemical smell.
That smell is the problem. PVC needs softening agents to be flexible, and those agents migrate out of the material over time — which is what you're smelling. A jelly dildo is porous, degrades quickly, and gets tacky as it ages.
If you already own one and want to keep using it, a condom over it is the standard advice. Better to replace it.
Glass and metal
Borosilicate glass and polished stainless steel are both entirely non-porous and completely sterilisable. They're also rigid, which some people specifically want, and they hold temperature — run them under cold or warm water first and the effect lasts.
They don't feel realistic and don't try to. Different category, both perfectly safe.
Latex and rubber
Older materials, still around at the very low end. Porous, degrade fast, and latex is a common allergen. There's no reason to choose these over silicone now.
=====================================================
What Dual Density Actually Does for You
The single biggest jump in realism in this category came from building toys in two layers instead of one.
A dual density dildo gives you four things a single-material toy can't:
It feels like skin under pressure. The surface yields when you press it, then springs back — the same way a body does. A single-pour toy is uniformly firm all the way through, and your hand knows the difference immediately.
It's more forgiving to use. Because the outer layer compresses, it enters more easily than its measurement suggests. At the same diameter, dual density is noticeably gentler than a rigid toy — which means you can go a size up without the jump being uncomfortable.
It holds its shape. It stays where you put it and takes pressure without folding. Soft single-density toys lose that as they get longer, and a piece that sags is a piece you fight with.
It looks right. The softer outer layer is what makes veining, skin texture and colour variation read as skin rather than as a moulded surface. Realism in photos is sculpting. Realism in your hand is this.
That combination is why dual density has become the standard for anything sold as realistic, and why the gap between it and a single-pour toy is bigger in use than it is in the specification.
=====================================================
Beyond Material: What Else Makes a Dildo Realistic
Material is the foundation, but three other things finish the job.
Sculpting. A mould taken from a real body, or sculpted by hand to match one, carries asymmetries that a CAD model doesn't — the slight curve, the uneven veining, the way the head meets the shaft. Perfectly symmetrical toys look manufactured because they are.
Colour. Realistic skin isn't one flat tone. Depth of colour, subtle variation along the shaft, a differently toned head — these are what stop a piece reading as a solid-coloured object. It's also the hardest part to do well, and where cheap "realistic" toys most obviously fall short.
Warmth. This is the one people forget. Silicone takes body heat and holds it; glass and metal don't, and porous materials lose it faster. Thirty seconds under warm water before use, and a silicone piece stops feeling like an object almost entirely.
=====================================================
How to Tell Real Silicone From Fake
Plenty of toys are marketed as silicone without being silicone. Three checks.
Smell it. Real silicone is odourless. A chemical or plastic smell means softening agents, which means PVC or a blend.
Stretch and pinch it. Silicone returns to shape immediately and the surface stays matte. TPE stays stretched slightly longer and feels tackier.
Check what it's compatible with. If the manufacturer says silicone lubricant is fine, it probably isn't silicone. Real silicone and silicone lube don't get along, and any honest manufacturer says so.
Price is the fourth signal, and it's blunt but reliable. Platinum-cured silicone costs several times what TPE does per unit. A full-size "silicone" toy at a very low price is almost certainly something else.

Frequently Asked Questions
What are dildos made of?
The common materials are silicone, TPE, TPR, PVC or jelly rubber, glass and stainless steel. Silicone is the most widely recommended because it's non-porous, chemically stable, and can be fully sterilised.
What is the safest dildo material?
Platinum-cured silicone, along with borosilicate glass and stainless steel. All three are non-porous, meaning they can be properly cleaned and won't harbour bacteria.
Are jelly dildos safe?
Jelly and PVC toys are porous and contain softening agents that migrate out of the material over time — which is what causes the chemical smell. They can't be sterilised. If you use one, use a condom over it, and replace it rather than keeping it long-term.
Are glass dildos safe?
Yes, when made from borosilicate glass, which is the same material used in laboratory glassware. It's non-porous, fully sterilisable, and much stronger than ordinary glass. Inspect for chips before each use and replace anything damaged.
What is a dual density dildo?
A toy built with a soft outer layer over a firmer inner core. The soft layer gives under pressure like skin, while the core holds the shape. It's more forgiving to use than a single-density toy of the same size, and it's what most realistic toys are built as.
Can I use silicone lube on a silicone dildo?
No. Silicone lubricant breaks down silicone over time, leaving the surface tacky. Use water-based lubricant with silicone toys.
How do I know if a dildo is really silicone?
It should be odourless, return to shape instantly when stretched, and the manufacturer should tell you not to use silicone lubricant with it. A chemical smell or a very low price point both suggest something else.
=====================================================
Material is what you'll notice first and what determines how long a toy lasts. Every piece in our realistic dildo range is platinum-cured silicone, built in two layers. If you're still deciding on size, the size guide covers length and girth.
