Silicone Dildo Firmness Guide: How to Choose the Best Option
Choosing the right silicone dildo firmness can completely transform your intimate experience. Whether you’re exploring realistic dildos, fantasy designs, or your first premium toy, understanding how firmness works will help you find the perfect match for your body and preferences.
At Erotixxx Toys, we hand-pour every toy using platinum-cured silicone that meets rigorous EPI-200-SIT safety protocols. That means you get precise Shore hardness levels, medical-grade safety, and complete customization every time. This guide explains everything you need to know about silicone firmness, from soft to firm options, so you can shop with confidence.
What Is Shore Hardness and Why Does It Matter?
Shore hardness is the scientific measurement that tells you exactly how soft or firm a silicone toy will feel. The Shore durometer scale is used worldwide to measure material resistance to indentation, and it’s the industry standard for body-safe silicone toys.
Most premium silicone toys use two scales: Shore 00 (softer materials) and Shore A (firmer materials). Lower numbers mean softer, squishier toys. Higher numbers mean firmer, more rigid toys. Even a 10-point change on the Shore scale creates a noticeable difference in how a toy feels during use.
Think of it this way: a soft gummy bear scores around Shore 00-30, while a firmer wine gum hits Shore A-40. Understanding this scale helps you choose exactly the sensation you want.
Silicone Firmness Levels Explained
Erotixxx Toys only uses platinum-cured silicone. This premium material stays body-safe at any Shore level and offers unmatched versatility. The main Shore hardness categories for our silicone toy firmness guide are:
Soft Silicone (Shore 00-30 to 00-50)
Soft silicone is as cushiony as it gets. These toys compress easily under light pressure but still maintain full structural integrity and safety standards. Soft firmness is ideal for long sessions, gentle stimulation, or anyone with sensitivity concerns.
Best for:
- Beginners exploring size or texture
- Extended wear or comfort-first users
- Sensitive anatomy
- Toys with intricate textures that benefit from flexibility
Medium Silicone (Shore 00-50 to A-10)
Medium firmness strikes the perfect balance between structure and comfort. This is the most popular choice for first-time buyers because it offers flexibility with just enough resistance to feel substantial.
Best for:
- Versatile, all-around use
- Users who want both comfort and stimulation
- Toys that need to stand upright on their own
- Balanced suction cup performance
Firm Silicone (Shore A-20 to A-40)
Firm silicone keeps its shape under pressure and delivers targeted, intense sensations. These toys provide concentrated pressure and are the best choice for suction cup stability and advanced users.
Best for:
- Precise G-spot or P-spot stimulation
- Advanced users seeking intense feedback
- Strong suction cup hold
- Designs that require stability during use

The Differences Between Soft and Firm Silicone Toys
Understanding how soft versus firm silicone dildo firmness changes your experience is essential for making the right choice.
Soft silicone toys deliver gentle, enveloping sensations that mold to your unique shape. They’re forgiving, comfortable, and ideal for beginners or anyone prioritizing ease of use. The trade-off is that softer toys may bend or compress during deeper play, especially in larger sizes.
Firm silicone toys provide targeted pressure and pronounced texture feedback. They maintain their shape, insert with more directional control, and deliver intense stimulation. Firm toys are perfect for experienced users who want maximum sensation and structural stability.
Medium firmness gives you the best of both worlds: comfortable flexibility with enough resistance to feel present and stimulating.
How to Choose the Best Firmness for a Realistic Dildo
One of the most common questions is: “What is the best firmness for a realistic dildo?”
The answer depends on what you’re looking for in your experience. Realistic dildos benefit from different firmness levels based on size, intended use, and personal preference.
Firmness by Size
| Size/Diameter | Soft | Medium | Firm |
| Under 1.5″ (Smaller) | Gentle starter for beginners | Balanced, comfortable | Intense, targeted stimulation |
| 1.5″–2″ (Medium) | Full feeling, easy to handle | Substantial, some flex | Strong presence, advanced users |
| Over 2″ (Larger) | Manageable stretch | Full sensation, some give | Extreme intensity |
For realistic dildos, medium to soft firmness mimics natural anatomy more closely. Some artisan makers describe firmness using “erection percentage”: Shore 00-30 feels like 40% erect, while Shore A-10 feels like 100-110% erect.
Longer realistic toys benefit from firmer silicone to prevent unwanted bending during deeper play. Shorter designs can handle extra softness without losing structural integrity.
How Size and Firmness Work Together
Size and firmness interact to determine overall comfort and sensation. A thick, soft toy can feel as gentle as a smaller, firm toy. That’s why it’s essential to consider both factors together.
Small toys in firm silicone deliver concentrated, intense stimulation. Large toys in soft silicone feel more manageable and forgiving during insertion and wear. If you’re new to larger sizes, starting with a softer firmness can make the experience more comfortable.

The Importance of Firmness Level in a Silicone Dildo
Firmness affects far more than just how a toy feels in your hand. It directly impacts sensation, ease of use, and even how textures are perceived during play.
Softer silicone compresses slightly during insertion, making textures feel gentler and dimensions more forgiving. This is ideal for extended sessions or users who want gradual, enveloping sensations.
Firmer silicone maintains full structural integrity, delivering more pronounced ridge and texture feedback. Every detail is felt more sharply, and the toy applies consistent pressure to targeted areas like the G-spot or prostate.
If you’re prioritizing suction cup performance, firmness matters even more. Toys in Shore A-20 and higher deliver the strongest hold, while soft silicone may need extra surface support.
Why Platinum-Cured Silicone Is the Safest Choice
At Erotixxx Toys, we only use platinum-cured silicone that meets EPI-200-SIT testing protocols. This ensures every toy is body-safe, non-porous, and free from harmful byproducts.
What Makes Platinum-Cured Silicone Different?
Platinum-cured silicone uses a platinum catalyst during the curing process, resulting in a cleaner, purer final product with no residual chemicals. Unlike peroxide-cured silicone, platinum-cured materials are hypoallergenic, non-toxic, and completely biocompatible.
According to research published by Healthline (2023), non-porous materials like platinum-cured silicone are essential for sexual health because they prevent microbial buildup and are easier to clean thoroughly.
Safety Certifications That Matter
Premium platinum-cured silicone is tested against stringent industry standards, including:
- USP Class VI Certification: Ensures biocompatibility and non-toxicity
- ISO 10993 Testing: Assesses cytotoxicity, irritation, and sensitization potential
- FDA CFR 177.2600 Compliance: Verifies safe use in repeated contact with the human body
These certifications confirm that platinum-cured silicone is safe for prolonged skin contact, has no harmful chemical migration, and does not trigger allergic reactions.

How to Care for and Clean Silicone Toys (All Firmness Levels)
One of the biggest advantages of platinum-cured silicone is how easy it is to clean and maintain, regardless of firmness.
Step-by-Step Cleaning Instructions
- Rinse immediately after use with warm water to remove surface residue.
- Wash with mild, unscented soap or a dedicated toy cleaner. Avoid harsh chemicals or alcohol-based products.
- For deep sterilization, boil your toy for up to 10 minutes. All firmness levels of platinum-cured silicone are heat-safe.
- Dry completely with a lint-free cloth before storing.
- Store in a breathable pouch to avoid lint attraction, especially for softer firmness toys.
Firmness-Specific Care Tips
Soft silicone attracts more lint and dust due to its tacky surface. Store in a dedicated lint-free bag and rinse before each use.
Firm silicone is the most durable and easiest to maintain. It resists tears, retains its shape nearly forever, and has a non-porous surface that stops bacteria buildup.

Frequently Asked Questions About Silicone Dildo Firmness
What Shore hardness is best for new users?
Start with medium firmness (Shore 00-50 to A-10). You’ll get balanced comfort and stimulation, making it the ideal middle ground before trying softer or firmer options.
What is the best firmness for a realistic dildo?
For realistic dildos, medium to soft firmness (Shore 00-30 to A-10) mimics natural anatomy most closely. Softer options feel more lifelike, while medium provides structure with realistic give.
Can I change my firmness selection after ordering?
Contact us within the first 24 hours to adjust your order. Once pouring starts, firmness cannot be changed, so we recommend experimenting over time with different firmness levels.
Does firmness affect suction cup strength?
Absolutely. Firmer silicone (Shore A-20 and up) delivers the strongest hold, while soft silicone may need extra support on some surfaces. Medium offers reliable suction for most uses.
Is boiling safe for every firmness level?
Yes. All our platinum-cured silicones are safe to boil for up to 10 minutes, regardless of Shore hardness. This is the most effective way to fully sterilize your toy.
Does temperature change how firm my silicone toy feels?
Warmth softens silicone slightly, while cooling increases firmness. Both effects are temporary and totally safe for the material. You can use temperature play to adjust sensation during use.
Do any adult toy makers offer a wide range of firmness options?
Yes. At Erotixxx Toys, every design is available in soft, medium, or firm. We hand-pour each toy to order, so you get complete control over firmness, color, and customization.
How Silicone Firmness Impacts Sensation
The impact of silicone firmness on sensation is one of the most important factors in choosing a toy.
Softer toys provide gentle, gradual pressure that molds to your anatomy. This makes them ideal for extended wear, comfort-focused play, or users with sensitivity. Textures feel rounded and forgiving.
Firmer toys deliver sharp, pronounced feedback. Every ridge, vein, and texture is felt more intensely. Firm silicone applies concentrated pressure to specific areas, making it perfect for G-spot or prostate stimulation.
If you’re exploring fantasy toys with intricate textures, medium firmness often provides the best balance: textures are clearly defined without being overwhelming.
Final Thoughts: Choose the Right Firmness for Your Perfect Experience
Choosing the right firmness is the single most important way to personalize your premium silicone toy experience. Whether you love the extra-cushion of soft, the reliability of medium, or the precision of firm, Erotixxx Toys gives you complete control with full customization at every step.
