Jelly toys can burn. I bought one a year or so ago and tried to use it a couple of times - and it felt like it was burning me. Very uncomfortable - to the point that I stopped using it completely. A few months later I was at my local sex shop and asked the clerk about it - she said that is a common problem. The chemicals in the toy's material are not so kind to delicate tissues.
I went home and threw it away.

I had the exact same thing happen with one of mine when I had noticed 'pieces' of it tearing away and as well talked to the sales woman about it - I threw out all my jelly toys and will now only use glass, silicone or metal
