I came across a site that sells glass dildos and was wondering if any LPSG members have tried any? If so do you have any preferences in brand, shape etc? Are there ones that are better than others? I am asking since I would like to purchase one. Some web sites claim that you can heat them up in hot water or stick them in the freezer for added sensation. Has anyone tried this? this particular website claims that they can make custom glass dildos as well, PassionGlass.com: Any information would be greatly appreciated.
