I've never been a dildo girl, myself. But, last week I purchased a glass one and a stone one. They are incredibly awesome. The "realistic" one I had didn't do anything for me. I used to use sleeves on my vibrators, but I think I've turned a corner, using the proper equipment.
The nice thing about glass is, there is so much variety. You can get any kind of texture or non-textured you want. I like the solidness of the natural products.
I am anxious to get some more glass dildos, and can't imagine they will be any less wonderful than the first.
