Glass is just wonderful. I love my glass pieces (I have a total of 4 and I will get more). I would warm them in warm water or you can cool them in cold water for sensations, they don't need a whole freaking bottle of lube, and they are totally body safe.
I did hit my cervix once with it (yeah, that was unpleasant), but once I was used to the length it was great. Honestly, even if you don't care for the look of yours, it should be one that can put good pressure on your g-spot...so you still win big!
