When shopping for a dildo, one of the first things you will notice is the different materials they are made from. Rubber dildos are usually cheaper, but they may not last as long or be easy to clean. Metal dildos are easy to sanitise, and you can heat or cool them for added fun. They also look sleek on your nightstand. Glass dildos are attractive, reliable, and easy to sterilise but less flexible. Silicone dildos are a popular choice because they are safe for the body, flexible, and come in many different designs. Don't forget to check the instructions for your dildo to see which type of lube works best with the material.
