Quick answer
Yes, glass dildos made from annealed, tempered borosilicate glass are completely safe for internal use. They are non-porous, hypoallergenic, and easy to clean, making them a durable and hygienic choice.
Why glass is a safe material
High-quality glass toys are made from tempered glass, which is heat-resistant and shatter-resistant. They are non-porous, meaning bacteria and mold cannot penetrate the surface, making them one of the most hygienic materials for sex toys. Unlike some plastics or jelly toys, glass does not contain phthalates or other harmful chemicals.
Temperature play: a unique advantage
Glass dildos conduct temperature exceptionally well. You can warm the toy under warm running water for a soothing sensation or cool it in the refrigerator (not freezer) for a thrilling chill. Always test the temperature on your inner wrist before insertion to avoid discomfort or injury.
Frequently Asked Questions
Is a glass dildo safe for anal use?
Yes, but only if the toy has a flared base or a handle to prevent it from slipping inside. Both the Cornstar and Bunny's Secret have a wide base that makes them safe for anal play. Always use a toy with a flared base for anal play.
How do I clean a glass dildo?
Wash with warm water and mild soap, or use a dedicated toy cleaner. You can also boil it for 3-5 minutes or run it through the dishwasher (top rack, no detergent) for a deeper sanitization. Glass toys can be boiled or dishwashed for thorough sterilization.
Can I use any lubricant with glass?
Yes. Glass is non-reactive, so it works with water-based, silicone-based, and oil-based lubricants. Silicone lube lasts longer and feels silkier, while water-based is easier to clean. Choose lubricant based on your preference, not compatibility.
How do I check for damage?
Before each use, inspect the toy under bright light for cracks, chips, or scratches. If you see any damage, discard the toy immediately to avoid injury. Regular inspection prevents accidents.
