I doubt that would be wise. Glass doesn't have any give, and it has the chance of breaking should you try to go about normally while wearing it. While this goes against every other piece of common wisdom, I'd suggest either purchasing a latex plug or using an oil-based lube, like vaseline. Alternately, a simple latex condom over one of your existing plugs should protect it nicely.
