🧪 1. Why Material Is So Important

The material of your sex toy is not a minor detail – it determines:

• Safety: Some materials release harmful substances (phthalates, BPA)
• Hygiene: Porous materials are not sterilizable and can harbor bacteria
• Feel & Sensation: Soft, firm, warm, cold – each material feels different
• Durability: Some toys last years, others crumble after months
• Lubricant Compatibility: The wrong lubricant can destroy the material
• Cleaning Effort: Not all materials are equally easy to disinfect

The most important distinction: porous vs. non-porous.

• Non-porous: Silicone, glass, metal, ABS plastic → hygienic, sterilizable
• Porous: TPE, TPR, PVC, latex → hard to clean, bacteria can settle

🧪 2. Silicone – The Gold Standard

Medical-grade silicone is the most commonly recommended material for sex toys – and for good reason.

Properties:

• Non-porous → hygienic and sterilizable
• Skin-friendly, hypoallergenic
• Body-warm – adapts to body temperature
• Flexible and soft, yet shape-stable
• Odorless (with high-quality products)
• Durable – lasts for many years with good care

Advantages:

• ✅ Safe for the body (body-safe)
• ✅ Can be boiled or sterilized with sex toy cleaner
• ✅ Pleasant, velvety feel
• ✅ No leaching of harmful substances
• ✅ Many hardness levels available (from very soft to firm)

Disadvantages:

• ❌ More expensive than TPE/PVC
• ❌ Not compatible with silicone-based lubricant (destroys the surface)
• ❌ Attracts dust and lint

Ideal for:

Anyone who values safety, hygiene, and durability. Especially recommended for anal toys, as these require particularly thorough cleaning.

Lubricant:

⚠️ Only use water-based lubricant. Silicone-based lubricant attacks the surface and makes the toy porous.

Cleaning:

Boiling (without vibrator electronics), dishwasher (top rack, without electronics), or with sex toy cleaner. Allow to dry completely.

🧪 3. TPE / TPR – Soft, Affordable, but with Catches

TPE (Thermoplastic Elastomer) and TPR (Thermoplastic Rubber) are the most common materials in the mid to lower price range. They often feel very realistic – soft, flexible, skin-like.

Properties:

• Porous → not fully sterilizable
• Very soft and flexible
• Often skin-colored and realistically textured
• Cheaper to manufacture
• May have its own odor

Advantages:

• ✅ Very realistic feel
• ✅ Affordable
• ✅ Soft and pleasant
• ✅ Phthalate-free (with high-quality TPE products)

Disadvantages:

• ❌ Porous – bacteria can settle in micropores
• ❌ Cannot be boiled or sterilized
• ❌ Can become brittle over time or "sweat" (plasticizers leach out)
• ❌ Sensitive to heat and some lubricants
• ❌ Not suitable for sharing without a condom

Ideal for:

Beginners on a budget, solo use, if the toy is replaced regularly. Less recommended for anal toys.

Lubricant:

✅ Water-based and silicone-based lubricants are generally compatible. Always test beforehand.

Cleaning:

Only with mild soap and lukewarm water or sex toy cleaner. Do not boil. Allow to dry completely, store dry.

🧪 4. Glass – Underestimated and Brilliant

Glass sex toys are one of the most underestimated products on the market. Once you've tried a high-quality glass dildo, you'll understand the enthusiasm.

Properties:

• Non-porous → perfectly hygienic
• Borosilicate glass (like Pyrex) – extremely robust and temperature-resistant
• Smooth, hard surface
• Temperature play possible (warm or cold)
• Heavier than silicone or TPE

🧪 7. Materials You Should Avoid

Not all materials on the market are safe. You should actively avoid these:

Material	Problem	Identifying features
PVC / Vinyl	Often contains phthalates (endocrine disruptors), porous	Cheap rubber smell, very cheap
Latex	Allergy risk, porous	Rubbery, latex smell
Jelly / Cyberskin	Porous, often phthalates, "sweats" plasticizers	Very soft, sticky, strong odor
Cheap TPE without certification	Unknown additives, porous	No manufacturer's proof, very cheap

Rule of thumb: If a toy has a strong smell (chemical, rubbery), that's a warning sign. High-quality materials are odorless or have very little odor.

You want the safest and most hygienic material:

→ Medical-grade silicone. No compromise, especially for anal toys.

You love intense, precise stimulation (G-spot, prostate):

→ Glass or metal. The hard surface hits spots that soft materials miss.

You want to try temperature play:

→ Glass or metal. Both absorb and retain temperature perfectly.

You're active in the BDSM scene:

→ Metal for weight stimulation, plugs, and control. Silicone for comfort during extended use.

You want a toy that lasts a lifetime:

→ Glass or metal. Virtually indestructible with proper care.

You share toys with a partner:

→ Silicone, glass, or metal – only non-porous, sterilizable materials. Or use a condom over TPE toys.

❓ 12. FAQ

Is silicone always safe?

Medical-grade or body-safe silicone, yes. Cheap "silicone" can contain fillers. Identifying feature: High-quality silicone toys are odorless and leave no indentation when pressed with a fingernail (silicone springs back, TPE remains indented).

Can glass really break?

Borosilicate glass (Pyrex quality) is extremely robust – more robust than regular glass. It does not break from normal use, only from a hard impact on hard surfaces. Briefly check for cracks before each use.

How do I recognize high-quality silicone?

Fingernail test: Press your fingernail into the material. Silicone will immediately spring back and leave no lasting indentation. TPE will remain indented for a short time. Also: no chemical odor, matte or velvety surface.

Can I use silicone-based lubricant with silicone toys?

No – this is one of the most common mistakes. Silicone-based lubricant attacks the surface of silicone toys and makes them porous. Always use water-based lubricant with silicone toys.

Which material is best for anal toys?

Silicone, glass or metal – exclusively non-porous materials. Anal toys must be able to be cleaned particularly thoroughly. TPE is not recommended for anal toys.

Are metal toys suitable for beginners?

Small metal anal plugs are also suitable for beginners – their weight and smooth surface even make insertion easier. Larger metal dildos are more for advanced users.

✅ 13. Conclusion

Choosing the right material is one of the most important decisions when buying a sex toy – and it depends on your priorities:

• Safety & Hygiene first: Silicone, glass or metal
• Realistic feel on a budget: High-quality TPE (phthalate-free)
• Precise stimulation & temperature play: Glass or metal
• Durability & investment: Glass or metal
• Flexibility & comfort: Silicone

Our clear recommendation: It's better to invest once in a high-quality silicone, glass or metal toy than multiple times in cheap TPE products that you have to replace regularly. Your body will thank you.
