Dark areas on dildo

I own some dildo, but one is giving me trouble. Some areas are becoming darker, like if there was a flame near it.

I only use water based lubes, nitrile gloves, and when I put my toys in their box, I wrap them individually in paper towel

It's from doc Johnson, isn't it a good brand? Link to dildo -> https://www.lovehoney.co.uk/product.cfm?p=22237

Thanks for feedback

Jelly dildos have a porous surface. I’m assuming you’re using it anally. You may wish to get a new one as it sounds like something is growing on it. If you’re going to use a jelly toy put a condom on it.

Dildos used anally can stain.

Sad, I clean them as much as possible everytime

It have 2 stains on the bottom which I never insert, strange

I just throw them out and buy a new one if it looks discolored. Just imagine the number of bacteria on that dildo!

Simply contact the company from which you bought it. There's nothing to be shy about. From my experience they have answered every question imaginable.
