A question about a vibrator that I have

Yes, it's time to throw it out. Jelly breaks down over time and some people are sensitive to jelly products. And I wouldn't call it an allergy...just a sensitivity...

You know, they often smell bad right out of the package, but you're probably talking about a different kind of smell.

I was gonna say, don't jelly toys always smell bad?

I agree with everyone else; condom it up, or get a phthalate-free toy. However, it's also possible you've got some sort of infection; it could be bacterial, viral, possibly an STI, or bacteria vaginosis (assuming you have a vagina). If changing a toy doesn't help, I really suggest heading to a doc to get it checked out. Infections in your nether regions are NEVER fun!

I’ve had this toy for over a year. I’ve had the same thing happen. In case you don’t want to throw it away (I don’t because I really like it) you can cover it with a condom so there is no direct skin to toy contact. Because jelly toys are porous and cannot be sterilized, it’s a good idea to use them with a condom at all times. The toy feels just as good even when it’s being safe.

Are you using a lubricant with this toy? It may possibly be the lubricant. Or possibly the product that you use to clean it with.

You should really stop using it. I'd recommend something made of medical grade silicone next time around.
