Both these materials are SILKY SMOOTH with the right lube, but FEEL very different. Steel has WEIGHT and HEFT. Glass has more temperature acclimation to the skin. Both are just...different and nice in their own way. If you have neither, START with glass...a simpler material to love. Steel can stay "cold" during non penetration play, and take some getting used to.
I've yet to try stainless steel, but am sure it's awesome! For now my favorite is glass!
It IS awesome. It is smooth as glass but still feels "different" to the skin. Most important, it NEVER has "breakage" worries and is, in a way, SMOOTHER then the glass...if you can believe that. Worth a try. I love my steel toys.
Steel toys might outlive you; not exactly the same as Grampa's pocket watch though. However, I've always thought glass toys were classy and sexy. I've always associated steel toys with BDSM/heavy play. So, what are you in the mood for: romantic or heavy play?
