Glass dildos are known for their elegance and unique feel. The weight, glide and hypoallergenic aspect make it a standout choice among all other types of sex toys for women and men. If you've ever wondered why glass dildos, you're not alone. They are a bit of an enigma in the sex toy world.
Looking at a catalog full of borosilicate glass toys can be a bit daunting because when it comes to hand-crafting glass objects of any kind, there is an unlimited size, shape and forms that can be created. It goes far beyond just adding liquid material into a dildo mold, glass is made differently and as such, they come in a vast array of textured and patterns.
Today's guide will help those considering adding borosilicate / Pyrex sex toys to their repertoire narrow down the search and choose one among the selection of varied textured and shapes that best suits their preferences and personal sexual desires.
Regardless if you're thinking about getting a glass dildo for vaginal use or a glass prostate toy for men, or wondering why anyone would want one of these in the first place, everyone will surely find useful tidbits of info in today's guide.
What Does a Smooth Glass Dildo Feel Like?
Glass is completely frictionless when wet. You can use any type of lube with it, or even water, but keep the shaft wet and the slippery feel is completely unique compared to any other dildo material. It's literally like a “slip 'n slide” for the vagina, lol.
The seamless design is best for those with sensitivities. If you find textured dildos or even a ribbed condom irritating, you'll appreciate the smooth sensation. A small or thin glass dildo typically measures 1 inch across making it the perfect choice for beginners and petite women (and anal play).
In comparison to other materials, smooth silicone dildos will still have a velvety touch even when well lubricated, but glass is completely slick. Lube can absorb into porous toys like some rubbers or PVC, but glass will never absorb liquids, so it stays slippery for longer.

What Does a Textured Glass Dildo Feel Like?
Textured glass toys can be very intense. In comparison to other material that have some flex and pliability, borosilicate is totally solid so the texture you see if the feel you get. There is no give when thrusting, the faster you go, the more wild the experience will be.
Spiraled glass toys are a nice compromise between thickly ribbed surface and smooth. You'll benefit from some texture but in a more gentle way. When using a heavily textured glass toy regardless of the size, we suggest going slow to avoid discomfort.
What About Safety?
Glass is safe – these dildos are solid and won't break or shatter if dropped. They have the same rigidity and durability as Pyrex bake ware, in fact, the borosilicate is the same as Pyrex!Comparing Borosilicate to Silicone, TPR & TPE
Silicone, TPR (thermoplastic rubber) & TPE (thermoplastic elastomer) are the three most common dildo materials. They feel comparable to each other, so we can combine these together in our comparison to glass.
Here is what makes glass dildos feel different compared to Silicone, TPR & TPE:
- Temperature play – It retains temperature much longer making glass dildos the best choice for temperature play. Put the toy in the freezer or dip it in hot water for a few minutes before using for an erotically thrilling sexual experience. This works equally well with both vaginal and anal play.
- Hypoallergenic & easy to clean – With the exception of medical-grade silicone & metal, glass is the only sex toy material that is completely non-porous and hypoallergenic making it the best sex toy for people with skin sensitivities. As a result, it is also the easiest to clean, simply wash with any type of soap and rinse with warm water.
- Sensual weighted sensation – Solid Pyrex dildos are heavy, much more so than other materials with the exception of steel or metal. (Aluminum is typically lighter in weight). The heavy feel is more intense providing the user with extra stimulation and a more substantial experience. A thick or large glass dildo will amplify the weighted sensation.
- Solid structure is best for G-spot & P-spot stimulation – A dildo or prostate massager that flexes or bends won't apply as much pressure to the G-spot or prostate gland compared to the unforgiving nature of glass. As a result, you will experience far more intense massaging sensations of the female G-spot and male P-spot.
