Has anyone else had a problem with the we-vibe 2 or 3 or in my case the Touch losing its sheen? I don't use silicone lubes so I'm wondering why the tip of my red we- vibe touch is dull? I don't overly use it as its about number 6 in my favs and probably have only used it less than 20 times. I only store it with the tango which is plastic so it's not that. Is this an okay thing? I don't have any other shiny silicone, jimmyjane form 2 comes close but not quite. Advice?
