I’m sorry to hear that your friend is having troubles with the toy, myself personally if a toy was giving me UTI’s I wouldn’t use it again.
The reaction could be coming from the material used to create the toy, and it’s having a reaction with your friend. Cyberskin toys are porous. They’re basically a form of jelly rubber – so they do contain chemicals ect. Because they are porous you can never fully clean it, bacteria can get inside the toy and well do what bacteria does and breed. You can only ever really clean the surface of these toys.
Personally the best thing would be to change the toy for a 100% Silicone toy, if she’s wanting the ‘real feel’ then a softer silicone would give her somewhat of a realistic feel granted not as much as Cyberskin would, however silicone is body safe and non-porous; where as CyberSkin isn’t. There are a few materials that are non-porous which are Glass, Stainless Steel, 100% Silicone, Ceramix (some wood – depending on what it is coated in) - And as I said with silicone you can get different 'firmness' of it. (I've heard Vixen dildos are quite good - Though I don't own one yet.)
To clean a Cyber Skin toy – is basically gentle soap and water and then put some corn starch on it. Don’t store them unless their 100% dry as they can then get mildew on them.
If she still wants to use the toy the only thing I could suggest is using a condom with it.
Thank you for your advice.
I was thinking that a condom would be her best bet if she really is keen to give it another go. I have to admit, I'm with you though - if a toy had given me a UTI I wouldn't be touching it again. But, I know that she's had a lot of trouble trying to find a dildo that she really enjoys, so I feel gutted that the one she found and loved isn't working for her!
I'll get her to look at some of the softer silicone dildos, hopefully she can find a suitable replacement.
