For at least 10 years, we have been warned (by sex educators, sex toy bloggers, and manufacturers,) not to use silicone lubes with silicone toys. The simple explanation was that silicone toys and lubes don't play well together; silicone lubes might degrade silicone toys over time. The resulting gummy texture was not pleasant, AND there would be no way to "restore" your toy or vibrator.
However, many of my customers LOVE their silicone lubricants, and LOVE their silicone toys...
SO, in the interest of the greater good, I have been doing some lube and toy testing.
Several of the toys we carry at Diva, from Fun Factory, Lelo, Tantus and We-Vibe were the subjects.
