What is a dildo – and what distinguishes a good one from a bad one?

What is a dildo?

A dildo is a penetration toy without vibration function – designed for vaginal or anal stimulation, alone or with a partner. The term covers a wide spectrum: from realistic penis replicas to fantasy shapes to dual-density constructions with a soft core and firm shaft. What all dildos have in common: shape, material, and texture determine the experience.

What distinguishes a good dildo from a bad one is not its shape – it's the material. A dildo has direct mucous membrane contact throughout its entire use. The material determines hygiene, safety, feel, and durability. No other factor is more important.

Why is silicone the best material for a dildo?

Silicone – especially platinum silicone – is the only material that meets all requirements for a body-safe penetration toy: non-porous (no bacterial accumulation), phthalate-free (no plasticizers), fully sterilizable, permanently dimensionally stable, and thermally conductive. TPE, PVC, and Cyberskin are cheaper – but porous, not fully sterilizable, and often contain plasticizers.

Dildo Types: Which one for which experience?

What dildo types are there – and what are the differences?

Realistic Dildo: Replicates human penis anatomy – glans, shaft, veins, realistic proportions. Primary appeal: familiar shape, realistic feel. Available in various sizes, skin tones, and materials. SilikonLust realistic dildos are made of dual-density silicone: soft outer layer, firm core – the most natural rebound feel silicone can achieve.

BBC Dildo (Big Black Cock): Realistic dildo with above-average size and dark skin tone. Primary appeal: size, fullness, visual appeal. For those seeking a more intense filling experience. More on this in our BBC Dildo Guide.

Fantasy Dildo: Interprets penetration shapes from fantasy aesthetics – dragon penis, tentacles, alien shapes, organic structures. Not human anatomy, but full functionality. Primary appeal: unusual textures, novelty-seeking, primal fetish. More on this in our Fantasy Dildo Guide.

Dual-Density Dildo: Two-layer construction – soft outer layer (skin-like feel), firm silicone core (stability and control). The most realistic rebound feel a dildo can achieve. Ideal for those seeking maximum realism in touch.

Anal Dildo: Optimized for anal use – conical shape for easy insertion, safety base (flared base) for safe use. Platinum silicone is particularly important for anal use: full sterilizability is non-negotiable for anal use.

Strap-On Dildo: Compatible with strap-on harness – for partner use. Firm base, stable shaft, harness-compatible shape. More on this in our Strap-On Collection.

Dildo Material: Why platinum silicone is the only standard

Which material is best for a dildo?

Material	Hygiene	Safety	Feel	Durability
Platinum Silicone	✅ Non-porous, sterilizable	✅ Phthalate-free, inert	✅ Silky matte, thermally conductive	✅ Durable, no aging
TPE	⚠️ Porous, not sterilizable	⚠️ Phthalates possible	⚠️ Degrades after months	⚠️ 12–18 months
PVC / Cyberskin	❌ Porous, bacteria breeding ground	❌ Phthalates, plasticizers	❌ Sticky, odor	❌ 6–12 months
Glass / Metal	✅ Non-porous, sterilizable	✅ Inert	⚠️ Hard, no flexibility	✅ Durable

What is dual-density silicone – and why is it better than simple silicone?

Dual-density silicone is a two-layer construction: a soft outer layer of platinum silicone (skin-like feel, elasticity) over a firm silicone core (stability, control). The result is the most realistic rebound feel a dildo can achieve – the outer layer yields like human tissue, while the core provides stability for precise control. SilikonLust realistic dildos use dual-density construction for maximum realism.

Buying a dildo: The 5 crucial buying criteria

What should you look for when buying a dildo?

1. Material (most important criterion): Platinum silicone or dual-density silicone. No other material simultaneously meets all requirements for hygiene, safety, and durability. For anal use, platinum silicone is non-negotiable.

2. Size and Diameter: Length and diameter should match your anatomy and experience. Beginners: 15–18 cm length, 3–4 cm diameter. Advanced: according to personal preference. Important: Diameter is often more crucial than length for the feeling of fullness.

3. Shape and Texture: Straight shaft: even stimulation, easy control. Curved shaft: G-spot or P-spot stimulation. Textured surface (veins, ribs, nubs): more intense stimulation. Fantasy shapes: unusual textures and geometries.

4. Suction Cup Compatibility: A suction cup at the base allows for hands-free use on smooth surfaces and strap-on compatibility. Equally valuable for solo and partner use.

5. Anal Safety (Flared Base): For anal use, a safety base (flared base) is absolutely essential – it prevents full insertion. Never use a dildo without a flared base for anal use.

Proper dildo use and care

How to use a dildo correctly?

Lubricant: Always use lubricant – even with sufficient

natural moisture. Water-based lubricant for platinum silicone – silicone-based lubricant will damage the material. More on this in our Lubricant Guide.

Preparation: Clean the dildo with warm water and mild soap before first use. For anal use: enema or thorough cleaning recommended. Moisten suction cup before attachment for maximum adhesion.

Positions: Hands-free with suction cup (wall, floor, chair), manually, with strap-on harness. Curved dildos for G-spot stimulation in a supine position with the shaft pointing upwards.

How to clean a platinum silicone dildo?

After each use: Wash with warm water and mild soap. Let dry completely.

Full sterilization:

• Boiling: 10 minutes – complete sterilization, especially important after anal use
• Dishwasher: Top rack, without detergent, 60–70°C
• Isopropyl alcohol 70%: Spray, 5 minutes, rinse thoroughly

Important for dual-density dildos: Do not boil – the soft outer layer cannot withstand temperatures above 80°C. Instead: soap + warm water or IPA 70%.

FAQ: Buying a dildo – the honest answers

What is the best dildo?

The best dildo is made of platinum silicone or dual-density silicone – non-porous, phthalate-free, fully sterilizable. Within this category, size, shape, and personal preference (realistic vs. fantasy, straight vs. curved) are decisive. There is no universally best dildo – but there is a universally best standard: body-safe silicone.

What dildo size is right for beginners?

For beginners, 15–18 cm in length and 3–4 cm in diameter are recommended. More important than length is diameter – it determines the feeling of fullness more strongly. Sufficient lubricant is mandatory for any size. Start slowly and listen to your own body.

What is the difference between a dildo and a vibrator?

A dildo has no vibration function – it stimulates through shape, texture, and movement. A vibrator has an integrated vibration function. Both can be used for vaginal or anal stimulation. Dildos are often more realistic in shape, while vibrators offer additional levels of stimulation.

Can a dildo be used anally?

Yes – with two prerequisites: The dildo must have a safety base (flared base) that prevents it from being fully inserted. And the material must be fully sterilizable – platinum silicone is the only hygienically acceptable standard for anal use. Sufficient lubricant is particularly important for anal use.

Which lubricant for a silicone dildo?

Water-based lubricant only. Silicone-based lubricant attacks silicone surfaces and permanently damages the material. Use generously – especially for anal use.

How to clean a platinum silicone dildo?

After each use: warm water and mild soap. Full sterilization: boil (10 minutes), dishwasher (60–70°C, without detergent) or isopropyl alcohol 70%. Do not boil dual-density dildos – instead, use soap or IPA.

What is a Fantasy Dildo?

A fantasy dildo interprets penetration forms from fantasy aesthetics – dragon penis, tentacles, alien shapes, organic structures. Not human anatomy, but full function. Primary appeal: unusual textures, novelty-seeking, primal fetish. More about this in our Fantasy Dildo Guide.
