Silicone-based lubeis slippery, long lasting, and is ideal for a longer session. It requires less lube be applied, and needs reapplication less often. Silicone-based lubes are also great for shower sex or masturbation in the shower, as they don’t wash away so easily. The catch is that silicone-based lubes are a bit more tedious to wash off, as you will need soap and water to clean up afterward. Sometimes silicone-based lubes may also stain sheets.(Word of caution: never spill a bottle of silicone-based lube on your hardwood floors—it will stain and leave your floor slightly slippery for months.)
Silicone-based lubricants should not be used with silicone-based sex toys, as they can break down the rubber over time. However, this doesn’t mean all sex toys are off limits with silicone-based lubricants—there are many toys made from other materials, like hard plastic, glass, and steel.
