Dildo Materials Guide

The material of a dildo can affect its firmness, flexibility, texture, weight, care requirements and overall feel. Because RealDildos carries products from multiple brands and suppliers, materials and formulations vary between products.

This guide explains common dildo materials and helps you compare their general characteristics. Always check the specifications and care instructions on the individual product page before purchasing or using an item.

These descriptions are general references. Material quality, formulation and manufacturing methods can vary significantly between products.

Silicone

Silicone is commonly used for dildos because it can be produced in a wide range of firmness levels, shapes and textures. Depending on the formulation, a silicone product may be soft and flexible, dense and firm, or somewhere in between.

Properly cured, intact silicone generally has a smooth, nonporous surface that is relatively easy to clean. However, not every product described simply as “silicone” will have the same softness, purity, finish or durability.

Common Silicone Characteristics

  • Available in soft, medium and firm formulations

  • Can reproduce detailed shapes and surface textures

  • May have a matte, silky, smooth or slightly tacky finish

  • Usually maintains its shape better than highly stretchy materials

  • Often heavier than similarly sized TPE or PVC products

  • May attract dust or lint, especially when very soft

Silicone Care

Clean the product according to the manufacturer’s instructions. Warm water and mild, unscented soap are suitable for many silicone products, but products containing motors, electronics, adhesives or multiple materials may have different care requirements.

Do not boil, soak or place a silicone product in a dishwasher unless the manufacturer specifically states that the entire product is suitable for that cleaning method.

Silicone Lubricant Compatibility

Water-based lubricant is generally the simplest option for silicone products.

Compatibility between silicone lubricant and silicone products varies by formulation. Some combinations may cause swelling, tackiness or surface changes. Check the product instructions and perform a small patch test on an inconspicuous area when compatibility is uncertain.

Dual-Density Silicone

Dual-density silicone products are designed with two different firmness levels. They typically have a firmer inner structure surrounded by a softer outer layer.

This construction can provide additional support while maintaining a softer surface feel.

Common Dual-Density Characteristics

  • Softer exterior with a more supportive core

  • May bend while returning to its original shape

  • Often feels more substantial than a single-density soft product

  • Can be heavier than similarly sized hollow or single-layer designs

  • Outer softness varies by brand and product

“Dual density” does not describe one standardized firmness. Two products using the same term may still feel significantly different.

Liquid Silicone

The term “liquid silicone” often refers to silicone processed from a liquid silicone rubber formulation. In product listings, it is commonly used to describe soft, flexible or highly elastic products.

However, the term does not automatically tell you the exact firmness, composition or quality of the finished item.

Common Liquid Silicone Characteristics

  • Soft and flexible

  • Smooth surface

  • May compress more easily than firmer silicone

  • Can be used for detailed or movable designs

  • May require additional support in larger sizes

Review the individual product’s firmness, construction and weight rather than relying on the term “liquid silicone” alone.

TPE and TPR

TPE means thermoplastic elastomer, while TPR means thermoplastic rubber. These terms cover broad families of flexible materials rather than one single formula.

TPE and TPR products are often soft, stretchy, lightweight and compressible. They may be used for realistic textures, flexible shafts, sleeves and products with a softer surface feel.

Common TPE and TPR Characteristics

  • Soft and flexible

  • Often lighter than solid silicone

  • May stretch or compress easily

  • Can provide a skin-like feel

  • May have a noticeable odor when new

  • May become tacky or change texture over time

  • Generally requires more careful cleaning and storage

TPE and TPR formulations can differ substantially. Firmness, odor, durability and care requirements may vary between brands and production batches.

TPE and TPR Care

Wash carefully according to the supplied instructions. Avoid harsh cleaners, high heat and aggressive scrubbing.

Allow the product to dry completely before storage. Store it separately because some soft materials may react when left in direct contact with other products.

Because many TPE and TPR formulations are more difficult to clean thoroughly than intact silicone, glass, metal or hard plastic, extra attention should be given to personal hygiene, individual storage and regular surface inspection.

PVC

PVC is a versatile material that can be made rigid or flexible. Soft PVC products contain additional ingredients that create flexibility, so the feel can range from firm to very soft.

Common PVC Characteristics

  • Available in many colors and textures

  • Can be flexible or relatively firm

  • Usually lightweight

  • May have a noticeable odor

  • Quality and formulation vary considerably

  • Surface condition may change with age, heat or improper storage

The word “PVC” alone does not provide complete information about the finished formulation. Follow the product-specific care instructions and discontinue use if the surface becomes cracked, peeling, unusually sticky or difficult to clean.

ABS Plastic

ABS is a hard plastic commonly used for handles, bases, internal structures, control units and rigid products.

Common ABS Characteristics

  • Firm and non-flexible

  • Smooth surface

  • Lightweight compared with glass or steel

  • Often used with motors or electronic components

  • May be combined with silicone or another soft material

An ABS product’s water resistance depends on its construction. Do not assume that a motorized product can be submerged simply because part of it is made from ABS.

Check whether the product is described as splash-resistant, water-resistant or fully waterproof, and follow the manufacturer’s instructions.

Glass

Glass products are known for their smooth, rigid surface and substantial feel. Products intended for intimate use are commonly made from durable glass, but the exact type and construction should be confirmed in the product description.

Common Glass Characteristics

  • Completely rigid

  • Smooth and low-friction surface

  • Nonporous when intact

  • Easy to inspect visually

  • Heavier than many soft materials

  • Can retain cool or warm temperatures

Glass Safety and Care

Inspect a glass product before every use. Do not use it if you see chips, cracks, deep scratches or other damage.

Avoid sudden or extreme temperature changes. Never heat a product in a microwave, oven, boiling water or open flame. Temperature play should remain mild, controlled and within the manufacturer’s instructions.

Do not use ordinary household glass or an object not designed for intimate use.

Stainless Steel

Stainless steel products are rigid, smooth and heavier than most other materials. The material can provide precise pressure and a substantial feel.

Common Stainless Steel Characteristics

  • Completely rigid

  • Smooth and nonporous when intact

  • Durable and easy to inspect

  • Heavier than silicone, plastic or aluminum

  • Retains temperature

  • Requires less product size to feel substantial because of its firmness and weight

Check the product description for the specified metal. “Metal” alone does not confirm that a product is stainless steel.

Metal Safety and Care

Inspect the surface for scratches, corrosion, rough edges or damaged coatings. Follow the manufacturer’s cleaning instructions and dry the product thoroughly before storage.

Avoid extreme heating or cooling. Test the temperature against the inside of your wrist before use.

Aluminum and Coated Metal

Aluminum products are typically lighter than stainless steel. They may have an anodized, polished, painted or plated surface.

The safety and care requirements depend on the finish. A damaged coating may expose the underlying material, so inspect the product regularly for scratches, peeling, chips or corrosion.

Do not continue using a coated product if its surface becomes damaged.

Blended and Multi-Material Products

Many products contain more than one material. Examples include:

  • Silicone exterior with a firm internal core

  • TPE surface with an ABS handle

  • Metal internal structure covered by silicone

  • Soft shaft attached to a plastic suction cup

  • Motorized products containing plastic, silicone, metal and electronic parts

  • Painted or coated decorative surfaces

When a product uses multiple materials, cleaning and storage should follow the requirements of the most sensitive component.

A product with a waterproof exterior is not necessarily fully submersible. Always check its stated water-resistance rating and instructions.

Understanding Material Terms

Product descriptions may use terms such as:

  • Body-safe

  • Medical-grade

  • Food-grade

  • Hypoallergenic

  • Platinum-cured

  • Skin-safe

  • Non-toxic

  • Eco-friendly

These terms should only be relied upon when supported by clear information from the manufacturer or supplier. They are not interchangeable, and they do not all describe the same property.

A marketing term alone cannot guarantee that a product will be suitable for every person. Individual sensitivities and reactions can vary.

If you have a known material sensitivity or allergy, review the complete material information and consult a qualified healthcare professional when appropriate.

Softness and Firmness

Material type is only one part of how a product feels. Products made from the same general material can have very different firmness levels.

Soft

Soft products compress and bend more easily. They may require additional support during use, particularly in larger sizes.

Medium

Medium-firm products balance flexibility and shape retention. However, “medium” is not standardized between manufacturers.

Firm

Firm products maintain their shape and provide more concentrated pressure. A firm product may feel more substantial than a softer product with identical dimensions.

Extra Firm or Rigid

Glass, metal and hard plastic do not compress. Their measurements should be considered carefully because their full diameter remains consistent under pressure.

Surface Texture

The surface finish can influence the overall feel as much as the material itself.

Smooth Finish

A smooth surface generally creates less friction and may be easier to clean.

Matte or Skin-Like Finish

A matte surface may provide a more realistic feel but can create additional drag and may attract dust or lint.

Textured Finish

Veins, ribs, bumps, ridges and knots can increase sensation. A textured product may feel larger than a smooth product with the same shaft diameter.

Coated or Painted Finish

Inspect coatings regularly. Discontinue use if the finish begins to peel, crack, chip, transfer color or develop rough areas.

Choosing Lubricant by Material

Lubricant compatibility depends on both the product material and the lubricant formula.

Product Material General Starting Option Important Notes
Silicone Water-based lubricant Check before using silicone-based lubricant
Dual-Density Silicone Water-based lubricant Patch-test other formulas if compatibility is unclear
TPE / TPR Water-based lubricant Avoid products not approved by the manufacturer
PVC Water-based lubricant Formulations vary; follow product instructions
ABS Plastic Water-based lubricant Check compatibility with coatings and attached materials
Glass Water- or silicone-based lubricant Consider any attached components
Stainless Steel Water- or silicone-based lubricant Check any coatings, handles or attachments
Multi-Material Products Water-based lubricant Follow the requirements of the most sensitive material

Water-based lubricant is generally the most broadly compatible starting option, but product-specific instructions should take priority.

Oil-based products can damage latex barriers and may be incompatible with certain soft materials. Check both the lubricant and barrier instructions before use.

Cleaning by Material

Material General Cleaning Approach Avoid Unless Specifically Approved
Silicone Warm water and mild, unscented soap Boiling or dishwashing products with motors or mixed materials
TPE / TPR Gentle washing with warm water and mild soap High heat, harsh cleaners and aggressive scrubbing
PVC Warm water and mild soap High heat and strong solvents
ABS Plastic Wipe or wash according to water-resistance instructions Submerging electronic products without confirmation
Glass Warm water and mild soap Extreme temperature changes and use when chipped
Stainless Steel Warm water and mild soap; dry thoroughly Extreme temperatures and abrasive cleaners
Multi-Material Follow manufacturer instructions Assuming every component has the same water resistance

Clean products before and after use. Rinse away soap residue where appropriate and allow the product to dry completely before storage.

Do not apply alcohol, bleach, acetone, perfume, household disinfectant or another strong chemical unless the manufacturer confirms compatibility.

Storage Tips

Proper storage can help protect the product’s surface and extend its usable life.

  • Clean and dry the product completely before storage.

  • Store products separately whenever possible.

  • Use a clean storage bag or container.

  • Keep products away from direct sunlight and excessive heat.

  • Avoid contact with sharp objects.

  • Do not place heavy objects on soft or hollow products.

  • Remove batteries during long-term storage when instructed.

  • Do not allow different soft materials to remain pressed together.

  • Inspect the product before every use.

Some soft materials can react with each other and become sticky, discolored or misshapen. Separate storage helps reduce this risk.

New Product Odor

Some materials, especially TPE, TPR and PVC formulations, may have a noticeable odor when first opened.

Allowing the clean product to air in a well-ventilated area may reduce a mild manufacturing or packaging odor. Do not use perfume, bleach or strong chemicals to mask the smell.

Stop using the product if the odor is unusually strong, becomes worse, causes irritation or appears together with leaking, sweating, stickiness or surface deterioration.

When to Replace a Product

Discontinue use if you notice:

  • Cracks, tears or splitting

  • Peeling or flaking

  • Deep scratches

  • Sharp or rough edges

  • Exposed wires or internal parts

  • Damaged coatings

  • Unusual swelling or distortion

  • Persistent stickiness that was not originally present

  • Leaking or oily residue

  • Mold or discoloration that cannot be cleaned

  • Persistent odor after proper cleaning

  • Corrosion or rust

  • A loose base, handle or motor housing

Do not attempt to repair a damaged insertable surface with household glue, tape, sealant or paint.
