Glass Dildos and Dilators: A Primer

Future Method

The Fun Stuff October 11, 2022

Like people (and penises), glass dildos and anal dilators come in a breadth of shapes, sizes, and of course, materials. Many of which, unfortunately, were not designed for the task from which their namesake is derived—dilation. I actually find this kind of amusing, because at least in the physical sense, dilation isn’t as complicated as you might think (trust me, as they say, I’m a doctor at this stuff). To make room for a more accommodating fullness, you’ll have two goals 1) fully opening the skin and strengthening it through varying, elevated pressures 2) full relaxation of the muscles underneath. There is, of course, the brain’s natural way of screwing this up (performance anxiety, clenching, inability to calm yourself), but with the right practice and preparation, these too can fade away. We are thrilled to share that leveraging Future Method’s science and anatomical knowledge of the anal canal + rectum we have developed our first 3-piece training system. You can think of it as a confidence workshop, but for your bum. But before we get into how to prime for pleasure—let’s talk more about the world of glass dildos and their close cousin, glass dilators.

What Is a Glass Dildo?

Glass dildos are sex toys (that should be) made out of smooth, non-porous Borosilicate glass. This makes them shatterproof. They can also come in a variety of shapes with different detailing for both pleasure and aesthetic.

Are Glass Dildos Safe?

It’s important to do your research and only purchase glass sex toys from trusted brands and retailers. Always choose a product made with Borosilicate glass to ensure they’re safe to use. If you drop a glass dildo, you should always stop using the dildo and replace it. Even if you can’t see any cracks or fractures—this is a must. Before each use, you should also check your toy for any cracks, chips, or fractures. Spot any? Cease using the toy and get a replacement. You can store them safely (and cleanly) in a soft place to ensure they live a long life.

Why Our Anal Dilation Kit

With so many options in the market, why did we decide to make our own set? Well for one, we’ve watched for years as brand’s experimented with shapes, materials, and sizes that simply didn’t fit (we mean this figuratively and literally). But also, Future Method fans had told us that they had not yet found a trusted source to prime before sex. To deliver on this need, we developed our Glass Anal Dilator Set, and here’s why we love it.

The Shape

A common misconception is that butt plugs, glass dildos, and anal dilators should have a phallic mold and be left inside you for extended periods of time. The true goal of anal training? Delivering gentle yet constant friction and pressure to all 3 sets of ring-shaped sphincters and the surrounding tissue so they gape (or remain) open. To properly strengthen and stretch these muscles, each dilator in our 3-piece kit was shaped with the ideal length and uniform circumference to meet these anatomical needs.


Glass, in your ass. Who would have thought? Both the anus and surrounding skin and tissue can be quite fragile. What needs to be created is tough tissue, sort of in the same way you build stronger calluses at the gym by lifting more and more weight. The Borosilicate glass that composes our dilators provides the ideal pressure to build this strength. It glides easily, but is strong enough to make a noticeable difference—pliability, relaxation, pleasure.

Size (There’s 3)

“Just stick it in,” just doesn’t work. Anal dilation takes time and everyone’s needs are different. Our 3-sized system allows the muscles and skin to fully accommodate through a graded sequential methodology. A recommended two weeks with Small and two weeks with Medium, until you graduate to Large. With the sexpertly sized and shaped Future Method Glass Anal Dilation Kit you get exactly what dilation should be: a relaxing, pleasurable, priming customized to your anatomy and readiness.

Glass Dildo Benefits

There are so many reasons why I love glass dildos and dilators and why I always recommend them to clients and friends alike:

  • Hygiene: Glass dildos are a great choice since glass is non-toxic, non-porous, phthalate-free, hypoallergenic, and won’t harbor bacteria. Because of their non-porous texture, they’re also very easy to wash and sanitize. Odorless is a nice perk, too (as we’ve all experienced the unworldly smell that silicone, PVC, and vinyl toys sometimes give off).

  • Aesthetic: Glass dildos come in plenty of shapes and colors. Many are handmade—works of art in their own right.

  • Weight: Glass dildos are weighted thanks to their material, which increases their pressure and pleasure. They’re also better at targeting G-spot and P-spot stimulation.

  • Temperature-adjusting: Glass dildos retain temperature well, allowing you to play with warm or cold sensations against the skin.

  • Waterproof: Non-porous and compatible with silicone lube, they’re perfect for the shower or bath.

  • Long-lasting: Thanks to their durable material, glass dildos last longer than other materials and don’t degrade over time.

  • Smooth exterior: Glass dildos have a smooth and slippery exterior that makes insertion easier.


How to Use a Glass Dildo

Using a glass dildo is similar to any other sex toy, but with some added considerations: Before usage, always check your dildo for any chips, fractures, or other damage. If you’re using your glass dildo for temperature play, place it in the fridge or in hot water to change its temperature. Just make sure it’s not too cold (otherwise it could cause cramping), or too hot (it could cause skin burns). I recommend finding a silicone lube and applying copious amounts to both the glass dildo and your anus. Don’t be afraid to reapply throughout the session.

How to Clean a Glass Dildo

Glass dildos are a breeze to clean, unlike other, porous materials. I recommend thoroughly sanitizing your glass dildo before and after each use. My preferred method is to rinse the glass dildo with water or wipe it with a damp paper towel or washcloth to remove any surface debris. Apply mild liquid soap and scrub well before rinsing with warm water. Once completely clean, place on a sterile towel and air-dry completely before storing in a soft, safe place.

There are also alternate ways to clean a glass dildo, which include:

  • Placing them in the dishwasher since they’re dishwasher-safe

  • Boiling the glass dildo in a pot of water

  • Using a sex toy cleaner and a clean cloth.

The Anal-tomical Choice

Glass dildos and anal dilators are important tools for anyone looking to get into anal play or perfect their bottoming game. With so many factors to consider— shape, size, material—one might say the simple act of choosing one that works for you has become a fairly complicated task. But it shouldn’t be. Our new 3-Piece Glass Anal Dilator Kit hits all the marks (and sphincters) because it was developed with an unparalleled understanding of your anatomy and the science of sex. We’re thrilled to bring this latest innovation – to help you take what you want, when you want, from whoever you want.
