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 a vibration function – designed for vaginal or anal stimulation, alone or with a partner. The term encompasses a wide spectrum: from realistic penis replicas to fantasy shapes to dual-density constructions with a soft core and a 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 the shape – it's the material. A dildo has direct mucous membrane contact throughout its use. The material determines hygiene, safety, feel, and longevity. 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 heat-conductive. TPE, PVC, and Cyberskin are cheaper – but porous, not fully sterilizable, and often contain plasticizers.

Dildo Types: Which one for which experience?

What types of dildos 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 shell, firm core – the most natural rebound feel that 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 in our BBC Dildo Guide.

Fantasy Dildo: Interprets penetration forms from fantasy aesthetics – dragon penis, tentacles, alien shapes, organic structures. Non-human anatomy, but full function. Primary appeal: unusual textures, novelty-seeking, primal fetish. More in our Fantasy Dildo Guide.

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

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: complete sterilizability is non-negotiable for anal use.

Strap-On Dildo: Compatible with strap-on harness – for partner use. Solid base, sturdy shaft, harness-compatible shape. More 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, heat-conducting	✅ 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 shell made 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 shell gives way 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 decisive 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 longevity. 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: uniform 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 use and partner use.

5. Anal Safety (Flared Base): For anal use, a safety base (flared base) is absolutely necessary – it prevents complete 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 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 a strap-on harness. Curved dildos for G-spot stimulation in supine position with the shaft pointed upwards.

How to clean a platinum silicone dildo?

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

Complete Sterilization:

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

Important for Dual-Density Dildos: Do not boil – the soft outer shell cannot tolerate 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 deciding factors. 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 more strongly determines the feeling of fullness. Plenty of 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. Learn more in our Fantasy Dildo Guide.
