I'd recommend the Gold Laced G. It was my first glass toy. It's gorgeous, has a non-intimidating slender shaft, the texture is also very subtle, it has a base so it can be used both vaginally and/or anally, and is inexpensive.
lol.thats' the one i was looking at. may i ask why you dont recommend that one?
Well, I wouldn't recommend it as a first glass toy because of how pronounced the nubs are. Texture on glass is not like texture on other toys because there is absolutely no give to the material. You may love nubs on a squishier toy but dislike them on glass. For a beginner, I'd recommend a toy with less texture, to allow the user to get a feel for the new material. The Nubby Wand isn't a bad toy, just not one I'd recommend to beginners. I own quite a few glas toys and don't actually use this one very much because I find the texture is way too much for me.
My first glass was the Rainbow swirl and it made me fall in love with glass. It has a slight curve for g-spot stimulation and some texture but it is mild for beginners. The Avalon is another good one. It's double ended. One side is a smooth thinner shaft and the other has bulges for that texture feeling.
