Silicone vs. Metal vs. Glass

Silicone, metal, and glass are three of the most common sex toy materials. So let’s take a look at the advantages and disadvantages of each.

Advantages of Silicone

  • Silicone can be anywhere from pillow soft to rock hard. Soft silicone feels wonderfully comfy.
  • Silicone is cheaper than body-safe metals and annealed glass.
  • Great silicone toys are far more plentiful than great metal or glass toys.

Disadvantages of Silicone

  • It’s almost always incompatible with silicone-based lube and sometimes incompatible with hybrid lube. To check, you need to do a spot test: Put a dab of lube on the toy’s base, then check back in ten minutes to see if the spot looks or feels any different. If nothing seems to have changed, it’s safe to use that particular lube with that particular toy.
  • The longest-lasting lube that’s compatible with silicone is coconut oil. I love coconut oil, but some people prefer silicone-based lube.
  • Though it happens much less often than it does with metal toys, many unscrupulous sellers falsely claim their products are silicone. You can often discern the truth from pictures if you’ve seen lots of silicone and non-silicone toys. You can also do a flame test. The results aren’t always clear-cut, but they can be really helpful.

Advantages of Metal

  • It’s mirror smooth, so it’s super easy to insert and remove.
  • Stainless steel is heavy and many people enjoy this sensation. There are weighted silicone plugs, such as b-Vibe’s Snug Plugs, but they’re not as heavy as their Pure Plug counterparts.
  • It’s compatible with all lubes, including silicone-based lube, which lasts a very long time.

Disadvantages of Metal

  • There’s only one big maker of well-designed, high-quality metal toys: Njoy.
  • So many metal toys claim to be made of a body-safe metal—that is, stainless steel, aluminum, or titanium—but are actually made of chrome-plated mystery alloys of dubious safety. If you think you’re getting a good deal on a cheap metal toy, you’re probably about to stick an unsafe metal in your body.
  • Body-safe metals are pricey.

Advantages of Glass

  • Like metal, it’s smooth.
  • It’s often cheaper than body-safe metals.
  • Like metal, it’s compatible with all lubes.

Disadvantages of Glass

  • There’s so much low-quality glass out there. Read this article on glass toy safety. If it’s cheap, it’s probably unannealed or poorly annealed.
