Hi I’m trying to find some answers as to why the flesh light I bought is deteriorating the way it does.

It’s happening on the back end, where there is no skin contact / friction.

The surface feels hard /sandy, with black and white bits. They don’t come off.

I use the fleshly daily, I rinse it and use water based lubricant and let it aerate.

There is no bad smell to it.

Any ideas?
