Glass can hurt if you're rough with it, but like with anything firm it's listening to your body and working with it.

glass don't hurt,,it depends on you people are different ,,if you feel attractive to glass then try it,, i have one and it does not hurt ,, see some reviews they're very helpful

One thing to remember with glass and other rigid materials: they have no give whatsoever, so they feel bigger than soft toys of the same diameter. It's advisable to go down a little in size compared to what you're used to when you first try glass. Also, because it's firm and heavy, you have to be gentle when you use it. Internal bruises aren't desirable.

But if you keep these things in mind, glass can be quite nice. And yes, lube is your friend, though glass is pretty smooth on its own and doesn't drag much. Too much lube can make it super-slippery.

Who prefers glass over jelly material?

If you like the softness and flexibility of jelly, go with silicone for something safe but still pliable. Just look for toys that don't have a hard core. If you want to try something firm, silicone skin on a hard core or glass is awesome, super safe, long lasting and a favorite for many. Jelly has a lot of drawbacks and safety concerns. I stay far away from jelly and other porous materials.
