Let's address the biggest fallacy around silicone-based lubes right off the bat - they are safe to use with condoms.
While we're on the topic of "safety" though, silicone-based lubes maynot begood to use with sex toys because the toys are typically made out of silicone and can be corrosive. While oil-based lubes can be used with sex toys,oil can be difficult to wash off, so water-based lubesmay be your best best for toy play.
Silicone lubes are usually described as silky. They're engineered to last a long time, and can help with fitting into tight spaces. You might find a few silicone lubes at your local pharmacy, but sometimes you'll have to visit an adult store, or buy online.
Silicone lubes aren't water soluble, so they're great for the shower or other wet places. That benefit can be a curse, that makes them more difficult to wash off, including sheets. We recommend grabbing a couple hand towels from the gym to catch any run off.
We're big fans of silicone lubes because they last a long time, work with condoms, and work in and out of the shower. It's worth trying a few different brands, because they all feel a little bit different.
