If you're using a toy that has a smell, please use a condom!
Toys that smell are usually, but not always, made from unsafe materials. The smell is "off gassing," meaning it's releasing chemicals, which may or may not be dangerous (pthalates don't have a smell, but they tend to be in toys that do have a smell).
If you want to stay away from smelly toys in the future, look for non-porous toys like pure silicone, metal, glass, or hard plastic .
