I have a g-spot glass wand with bumps rather than ridges.
I got mine pretty early on in my sex toy exploration. I have been inlove with it forever. It milks my g-spot quite well and gets me squirting like crazy. It's so smooth when it glides in and out compared to silicone toys which have a bit more drag or friction.
If you would be intrested in a glass toy there are some really nice inexpensive options that can give you a taste of what these are like.
And a fun little aspect of glass is that you can play with its temperature (cool/warm) depending on what you like.
