1. Silicone Dildos: Safe, Soft, and Versatile

If you’re new to sex toys, you’ve probably seen silicone dildos pop up everywhere—and for good reason. Silicone is kind of the gold standard. It’s body-safe, hypoallergenic, and super versatile. Whether you want something firm or soft, silicone can offer both. Plus, it warms to your body temperature, making everything feel a little more natural.

Why You’ll Love It:

  • It’s body-safe, non-porous, and hypoallergenic.
  • Flexible and soft, but still firm enough to hit the right spots.
  • Comes in various textures and designs.

Quick Tip: Stick to water-based lubes with silicone dildos to avoid damaging the material.

Best For: Anyone looking for a reliable, body-safe option that’s great for both beginners and pros.

2. Glass Dildos: Elegant and Firm

Okay, I know what you’re thinking—glass dildos? But hear me out! Glass dildos are smooth, firm, and surprisingly fun. Made from body-safe tempered glass, these toys are durable, easy to clean, and non-porous. Plus, they can be heated or cooled for some temperature play, which is a cool (or hot) way to mix things up. If you like precise stimulation, glass could be your new best friend.

Why You’ll Love It:

  • The firm texture is perfect for deep, targeted pleasure.
  • Temperature play! You can heat or cool them for different sensations.
  • Super easy to clean—just soap, water, and you’re done.

Safety Note: Always check for cracks or chips before using glass dildos. Even though they’re durable, it’s better to be safe!

Best For: People who like firm, precise stimulation and want to experiment with temperature play.

3. Metal Dildos: Sleek, Cool, and Intense

If you’ve ever wanted a toy that feels as sleek as it looks, metal dildos are definitely worth a try. Made from stainless steel or aluminum, these toys are smooth, heavy, and offer a whole different kind of intensity. Like glass, they can be used for temperature play, but they’re a little heavier, which adds a deep, luxurious feel.

Why You’ll Love It:

  • The weight adds extra pressure for deep stimulation.
  • Can be heated or cooled, just like glass dildos.
  • Non-porous and super easy to clean.

Safety Tip: Metal dildos are firm and weighty, so take your time and adjust to the intensity. It’s all about balance!

Best For: Those who enjoy intense, deep sensations and want something a little extra luxurious.

4. Jelly Dildos: Soft but Watch Out for Safety

Jelly dildos might catch your eye because they’re squishy and affordable, but they come with some caveats. While they’re super soft and flexible, jelly dildos are porous, meaning they can harbor bacteria if not cleaned properly. Some also contain harmful chemicals like phthalates, so if you go this route, be sure to use a condom over the toy.

Why You’ll Love It:

  • Soft and squishy for a gentler experience.
  • Budget-friendly option.

Safety Tip: Always use a condom with jelly dildos to keep things clean and safe, and wash them thoroughly after every use.

Best For: Those who prefer softer, flexible toys but are mindful of safety precautions.

5. Cyberskin Dildos: Ultra-Realistic

If you want a toy that feels as close to the real thing as possible, cyberskin dildos are designed with lifelike textures. They’re soft, stretchy, and incredibly realistic. However, much like jelly dildos, they’re porous and need extra care when cleaning. Cyberskin is also a little more delicate, so you’ll want to handle it with care to avoid tearing.

Why You’ll Love It:

  • The most realistic texture—feels like skin.
  • Soft, stretchy, and very lifelike.

Safety Note: Clean thoroughly after every use and store your cyberskin dildo separately to avoid damage.

Best For: Those looking for the most realistic feel possible.

6. Dual-Density Dildos: Soft Meets Firm

Looking for something that feels like the real deal? Dual-density dildos combine a firm inner core with a soft outer layer, giving you the best of both worlds. You get the structure and firmness you need with the softness and flexibility that makes the experience feel more natural.

Why You’ll Love It:

  • Realistic feel with a soft outside and firm inside.
  • Combines the best of both firm and flexible dildos.

Safety Tip: Most dual-density dildos are made from body-safe materials like silicone, but always check the label to be sure.

Best For: Anyone looking for a lifelike experience with both softness and firmness.

7. TPE and TPR Dildos: Soft, Squishy, and Porous

TPE (thermoplastic elastomer) and TPR (thermoplastic rubber) show up on a lot of lower-cost toys, especially realistic ones. They feel softer and stretchier than most silicone, and some people love that squishy, skin-like give.

The trade-off is hygiene. TPE and TPR are porous, so they can hold on to bacteria and residue no matter how well you wash them. If you go this route:

  • Use a condom over the toy, especially if you share it or switch between anal and vaginal play.
  • Wash it with warm water and mild, fragrance-free soap after every use, then let it air-dry completely.
  • Never boil it. Heat can warp or melt these materials.
  • Replace it once it looks cloudy, sticky, or stained, or starts to smell.

A Quick Word on Jelly and PVC

"Jelly" is not really a material of its own. It usually means PVC that has been softened with plasticizers, which is where the phthalate worry comes from. If a toy is labeled jelly, has a strong chemical smell, or feels oily or tacky out of the box, treat it like the jelly toys above: condom on, short sessions, and replace it sooner rather than later. When in doubt, pick silicone, glass, or stainless steel instead.

Caring for Metal Dildos

Stainless steel is the easiest metal to live with. It is non-porous, so a wash with warm water and mild soap is usually all it needs, and plain stainless steel can be boiled for a deeper clean. Aluminum toys are lighter, but they are often coated or anodized, so skip boiling and harsh cleaners unless the maker says otherwise.

  • Test the temperature on your wrist before using a warmed or chilled toy. Use warm water or the fridge, never a microwave, stovetop, or freezer.
  • Any lube works with stainless steel, including silicone-based lube.
  • Dry it fully and store it in a soft pouch so it does not scratch, or get scratched by, your other toys.
  • Check the surface now and then. Retire anything with deep scratches, rough seams, or flaking finish.

How Dildos Are Made

Knowing how a toy is made helps you understand why two dildos that look alike can feel so different. The process changes with the material, but most soft toys follow the same basic path.

  • Molding: Liquid silicone or melted TPE is poured or injected into a mold. The mold sets the shape and every surface detail, from smooth fantasy curves to veins and ridges on a realistic toy.
  • Curing: Silicone has to cure, a chemical setting process that is often sped up with heat, before it holds its shape. TPE simply cools and firms up. Properly cured silicone stays soft and flexible without feeling sticky.
  • Dual-density layering: Dual-density dildos are made in two stages. A firmer inner core is cast first, then a softer outer layer is poured around it in a second mold, so you get a toy with a solid core and a plush surface.
  • Finishing: The toy is removed from the mold, seams and rough edges are trimmed, and color or texture details are added.
  • Testing and packaging: Good makers check for defects, clean the toys, and seal them for sale.

Glass and metal are a different story. Glass dildos are shaped by hand or in molds from borosilicate glass, then annealed (slowly cooled) so the glass is strong and stable. Steel toys are machined and polished until the surface is smooth.

Glass vs Silicone Dildo: Which Is Better?

Neither is better for everyone. A silicone dildo has a little give, warms to body temperature and suits most people, but pair it with water-based lube. A glass dildo is completely rigid, smooth and non-porous, works with any lube and can be warmed or cooled for temperature play, which makes it good for firm, precise G-spot or P-spot pressure. Choose silicone for comfort and flexibility, glass for firmness and easy cleaning, and check any glass toy for chips before each use. Compare options in our glass dildos collection.
