When shopping for a dildo, most people focus on size, shape, or features — but material is often the most important factor. It directly affects safety, comfort, durability, and even pleasure. Understanding what your toy is made of can save you from potential health risks and ensure a better, more satisfying experience.
Dildo Materials Guide: How to Choose the Safest and Best Material
When choosing a dildo, size and shape usually get most of the attention. But the material can be just as important.
It affects how the toy feels, how flexible or firm it is, how easily it can be cleaned, which lubricants you can use, and how long the toy is likely to last.
One of the most useful distinctions to understand is porous vs. non-porous materials.
For insertable toys, non-porous materials such as 100% silicone, borosilicate glass, stainless steel, aluminum and quality hard plastic are generally easier to clean and maintain. Softer materials such as TPE, TPR, jelly rubber, PVC and some elastomer blends may feel extremely realistic, but they usually require more careful hygiene and storage.
If you are comparing overall construction as well as materials, our high-quality dildo choices guide explains how material, firmness, shape and other features work together.
Quick Comparison: Which Dildo Material Is Best?
The exact composition can vary between manufacturers, so always check the product specifications and care instructions.
Why Dildo Material Matters
Material changes much more than the surface texture of a toy.
Hygiene
Non-porous materials do not readily absorb fluids and are generally easier to clean thoroughly.
Porous materials may retain moisture and microorganisms within microscopic spaces in the material, which is why they require more careful cleaning, drying and storage.
This distinction becomes especially important when a toy is shared between partners.
Comfort
A soft material can flex and compress with the body, while rigid materials such as glass and stainless steel provide much stronger and more concentrated pressure.
Neither is automatically better. The right choice depends on the sensation you prefer.
Realism
People looking for a realistic dildo sometimes assume that the softest material will automatically feel the most lifelike.
TPE and TPR can indeed be exceptionally soft and compressible, but softness is only part of realism.
Material density, surface texture, flexibility, shaft shape and internal construction also affect how a toy feels.
Modern dual-density silicone uses a firmer internal core combined with a softer exterior. This can provide a combination of structural support and surface softness without relying on porous real-feel materials.
For a closer look at these differences, see our guide to real-feel dildos and the features that create a realistic sensation.
Durability
Material also affects how a dildo ages.
Quality silicone, stainless steel and borosilicate glass can potentially last for years when properly used and maintained.
Softer thermoplastic materials may gradually become sticky, discolored, cracked or otherwise deteriorated.
Any toy showing significant surface deterioration should be replaced.
1. Silicone Dildos
For many users, 100% silicone is one of the most practical materials for an insertable toy.
Silicone can be manufactured in different firmness levels. Some products are very soft and flexible, while others are considerably firmer.
Advantages of silicone
- Non-porous when made from 100% silicone
- Available in different firmness levels
- Flexible and comfortable
- Durable
- Relatively easy to clean
- Suitable for detailed realistic designs
- Warms naturally during use
Disadvantages of silicone
- Usually more expensive than basic TPE or jelly materials
- Some soft silicone surfaces attract lint and dust
- Silicone-based lubricant may not be compatible with silicone toys
- Products described simply as a “silicone blend” may not have the same properties as 100% silicone
What Is Dual-Density Silicone?
Dual-density construction is particularly useful in realistic dildos.
A firmer internal section provides structural support while a softer silicone exterior provides more compression and flexibility.
This allows manufacturers to create toys that feel softer on the surface without making the entire shaft extremely flexible.
For people looking for a combination of realistic softness, durability and easier maintenance, dual-density silicone can be an attractive option.
2. TPE and TPR Dildos
TPE stands for thermoplastic elastomer, while TPR generally refers to thermoplastic rubber.
These materials are frequently used in realistic toys because they can be extremely soft, stretchy and compressible.
Advantages
- Very soft
- Highly flexible
- Can produce a skin-like texture
- Usually less expensive than premium silicone
- Suitable for highly detailed realistic designs
Disadvantages
TPE and TPR are generally considered porous or potentially porous materials.
That means they require more careful hygiene than non-porous silicone, glass, metal or hard plastic.
They can also deteriorate more quickly.
Signs that it may be time to replace a TPE or TPR toy include:
- permanent stickiness or tackiness
- cracks or tears
- persistent odor after cleaning
- significant discoloration
- changes in surface texture
- visible deterioration
When a porous toy is shared, using a new condom over the toy for each user can provide an additional barrier.
Silicone vs. TPE: Which Is Better?
This is one of the most common questions when choosing a realistic dildo.
There is no universal winner because the two materials prioritize different qualities.
Choose silicone if you prioritize:
- easier cleaning
- long-term durability
- a non-porous surface
- lower maintenance
- a wide range of firmness levels
Consider TPE or TPR if you prioritize:
- maximum softness
- high flexibility
- a very compressible texture
- lower initial cost
For many users, dual-density silicone provides a useful middle ground, combining a soft exterior with the durability and easier maintenance associated with silicone.
3. Borosilicate Glass Dildos
Quality borosilicate glass provides a completely different sensation from silicone or TPE.
Instead of flexing or compressing, glass remains rigid.
That means relatively small movements can create strong, focused pressure.
Advantages
- Non-porous
- Extremely smooth
- Easy to clean
- Durable when properly manufactured and handled
- Compatible with common lubricant types
- Suitable for temperature play
- Provides precise pressure
Disadvantages
- Completely rigid
- Can feel intense
- Heavier than many silicone toys
- Must be inspected for chips, cracks or other damage before use
Glass toys can also be warmed or cooled in water to change the sensation.
Avoid extreme temperatures and follow the manufacturer’s instructions.
4. Stainless Steel Dildos
Stainless steel toys are among the most durable options available.
Their weight and rigidity create substantially different sensations from flexible silicone and TPE.
Advantages
- Non-porous
- Extremely durable
- Smooth surface
- Easy to clean
- Suitable for temperature play
- Compatible with common lubricant types
- Additional weight can create stronger pressure
Disadvantages
- Usually expensive
- Heavy
- Completely rigid
- May provide more pressure than some users prefer
For people who specifically prefer weight and firmness, stainless steel provides sensations that soft materials cannot reproduce.
5. ABS Plastic
ABS is a rigid plastic commonly used in vibrators and other sex toys.
It does not provide the realistic softness associated with silicone or TPE, but quality ABS has several practical advantages.
Advantages
- Hard and smooth
- Lightweight
- Non-porous
- Easy to clean
- Durable
- Usually relatively affordable
Its biggest limitation for realistic dildos is simply that rigid plastic does not reproduce the softness or flexibility of body tissue.
6. Jelly, PVC and Other Soft Blends
“Jelly” is not one specific material.
The term can describe several soft plastic or rubber-like formulations, which makes the manufacturer’s material disclosure particularly important.
These products are often inexpensive and highly flexible, but many jelly, PVC and similar rubbery materials are porous or potentially porous.
If a product description only says things such as:
- “jelly”
- “rubber”
- “realistic material”
- “skin-like material”
- “premium blend”
without identifying what the product is actually made from, it is worth looking for more detailed specifications before purchasing.
Material transparency is more useful than vague marketing terminology.
Porous vs. Non-Porous Dildos
Understanding porosity makes choosing and caring for a toy much easier.
Non-Porous Materials
Common examples include:
- 100% silicone
- borosilicate or break-resistant glass
- stainless steel
- aluminum
- quality hard plastic such as ABS
These materials are generally easier to clean because fluids and microorganisms are less likely to penetrate the surface.
Porous or Potentially Porous Materials
Examples may include:
- TPE
- TPR
- jelly rubber
- PVC
- vinyl
- silicone blends
- some elastomers and rubber-like plastics
These materials generally require more careful hygiene, complete drying and appropriate storage.
If you are unsure which category a product belongs to, check the manufacturer’s exact material specifications rather than relying only on terms such as “body-safe” or “real feel.”
Material Is Not the Only Thing That Changes How a Dildo Feels
Two toys made from similar materials can still feel dramatically different.
Overall length is only one measurement.
Other characteristics include:
- insertable length
- shaft diameter
- head diameter
- firmness
- flexibility
- shaft curvature
- weight
- surface texture
- base design
For example, two products both listed as 7 inches long may have very different insertable lengths if one has a large anatomical base.
Likewise, a soft dual-density shaft can compress under pressure while a firm single-density shaft maintains its full diameter.
Our guide explaining why two dildos with the same length can feel completely different looks at these differences in more detail.
Which Lubricant Should You Use With a Dildo?
Lubricant compatibility depends on both the toy material and the lubricant formulation.
Water-Based Lubricant
Water-based lubricant is generally the simplest universal option.
It is compatible with the major materials commonly used for sex toys, including:
- silicone
- TPE and TPR
- glass
- stainless steel
- ABS plastic
Water-based lubricant is therefore a practical default when you are unsure about compatibility.
Silicone-Based Lubricant
Silicone lubricant is long-lasting, but it should generally not be used with silicone toys unless the manufacturer specifically confirms compatibility.
Silicone-based lubricant can interact with some silicone materials and damage or alter the surface.
It is generally compatible with glass, metal and non-porous hard plastics.
Oil-Based Lubricant
Oil-based lubricants require more caution.
They can damage latex and polyisoprene condoms and are not recommended with some porous plastics and synthetic rubber materials.
They are generally compatible with glass, metal and many non-porous hard plastics.
Because toy formulations differ, manufacturer instructions should always take priority.
How to Clean a Dildo
The correct cleaning method depends on the material and construction of the toy.
For routine cleaning, many toys can be washed with warm water and mild soap.
Always follow the manufacturer’s instructions, especially for:
- vibrating toys
- rechargeable products
- toys with electrical components
- porous materials
- products made from multiple materials
Some solid silicone, glass or stainless-steel products may tolerate higher-temperature cleaning or other disinfection methods, but do not assume that a toy can be boiled or placed in a dishwasher unless the manufacturer specifically confirms it.
Clean toys before and after use and allow them to dry completely before storage.
When sharing toys, using condoms can provide an additional barrier. Use a new condom when changing users and when moving a toy from anal to vaginal use.
For detailed cleaning methods, storage advice and replacement signs, see our complete care, storage and replacement guide for realistic dildos.
How to Store Different Dildo Materials
Storage is an important part of toy care.
After washing, allow the toy to dry completely before putting it away.
Ideally, store toys separately in individual pouches, bags or containers.
This is especially useful for softer materials because different formulations may react when stored in direct contact for long periods.
Separate storage also helps protect surfaces from:
- dust
- lint
- direct sunlight
- excessive heat
- contact with other materials
- dyes from fabrics or other products
Always follow any specific storage instructions supplied by the manufacturer.
How to Tell Whether a Dildo Uses a Quality Material
Price alone does not tell you whether a material is suitable.
Before purchasing, look for several things.
Clear Material Disclosure
The manufacturer or retailer should clearly explain what the product is made from.
Terms such as “premium material,” “skin-like” or “real feel” do not identify the actual material.
Cleaning Instructions
The product should provide information explaining how it should be washed, dried and maintained.
Lubricant Compatibility
Look for instructions explaining which lubricants can safely be used with the product.
Manufacturer Information
Choose products from manufacturers or retailers that provide clear product specifications and contact information.
Relevant Safety Information
ISO 3533:2021 is an international standard covering safety and user-information requirements related to the materials and design of manufactured sex toys intended for direct genital and/or anal contact.
Marketing terms such as “medical grade,” “premium” or “body safe” should not replace clear information about the actual material and construction of the product.
Which Dildo Material Feels Most Realistic?
For pure softness and compressibility, TPE and TPR can provide a very lifelike texture.
However, softness alone does not determine realism.
A quality dual-density silicone dildo can combine:
- a soft outer surface
- a firmer internal structure
- anatomical detailing
- flexibility
- durability
- easier maintenance than porous materials
For this reason, people shopping specifically for a realistic dildo should compare material, firmness and construction, rather than simply choosing the softest product.
If you want to compare different realistic designs after choosing a material, see our guide comparing realistic dildo options and features.
What Is the Best Dildo Material for Beginners?
There is no single material that works for everyone.
However, quality 100% silicone is a practical starting point for many users because it combines flexibility, durability and relatively straightforward care.
A beginner may want to look for:
- a smooth surface
- moderate flexibility
- manageable diameter
- tapered or rounded shape
- clearly disclosed material
- water-based lubricant
For anal use, material is only part of the safety equation.
Any toy intended for anal insertion should have a wide flared base or another reliable retrieval feature that prevents the entire toy from entering the rectum.
Frequently Asked Questions
What is the safest dildo material?
There is no single material that is automatically best for every product.
For insertable toys, non-porous materials such as 100% silicone, stainless steel, aluminum, quality hard plastic and break-resistant glass are generally easier to clean and maintain.
Clear material disclosure, appropriate design and manufacturer care instructions are also important.
Is silicone better than TPE?
They offer different advantages.
Silicone generally provides easier maintenance, greater durability and a non-porous surface.
TPE can be softer and more compressible but is generally porous and therefore requires more careful cleaning and storage.
Are TPE dildos safe to use?
TPE is widely used in sex toys, but it is generally considered porous or potentially porous.
Follow the manufacturer’s cleaning and care instructions, allow the toy to dry completely and replace it if its surface begins to deteriorate.
A condom can provide an additional barrier, particularly when a porous toy is shared.
Can you use silicone lubricant with a silicone dildo?
Generally, it is safest to avoid silicone lubricant on silicone toys unless the manufacturer specifically confirms that the combination is compatible.
Water-based lubricant is the most universally compatible option.
Can you use oil-based lubricant with a dildo?
It depends on the material.
Oil-based lubricants are generally compatible with glass and metal but can damage latex condoms and may be incompatible with porous plastics and synthetic rubber materials.
Check both the toy and barrier manufacturer’s instructions.
Can you boil a silicone dildo?
Some solid 100% silicone toys may tolerate boiling, but this does not mean that every silicone toy should be boiled.
Products containing motors, batteries, electronic components, adhesives or multiple materials may be damaged.
Always follow the manufacturer’s cleaning instructions.
How long does a dildo last?
There is no universal replacement schedule.
Durable non-porous materials such as quality silicone, glass and stainless steel can last for years when properly maintained.
Replace a toy if you notice:
- cracks
- tears
- permanent stickiness
- persistent odor
- significant discoloration
- damaged surfaces
- material deterioration
- structural damage
Final Thoughts
The best dildo material depends on the sensation, durability and level of maintenance you want.
For a versatile combination of flexibility, durability and easier cleaning, quality 100% silicone is one of the most practical options.
For maximum softness and a highly compressible, realistic texture, TPE or TPR may feel more lifelike, but these materials generally require more careful hygiene and may have a shorter useful lifespan.
For people who prefer strong, precise pressure, borosilicate glass or stainless steel provide a completely different experience.
Most importantly, look beyond marketing language.
Check:
- the exact material
- whether it is porous or non-porous
- manufacturer cleaning instructions
- lubricant compatibility
- product condition
- design appropriate for its intended use
Choosing the right material does more than change how a dildo feels. It affects how the toy should be used, cleaned, stored and maintained throughout its lifespan.
