I have a few platinum cure silicone toys, and I recently acquired a riding pillow set. I'd really like to use my silicone toys with the pillow, and I've discovered that putting a cock ring on the dildo will allow me to strap it on. I've tried this once, quite successfully, using a cock ring made of TPR.

Now, I wouldn't mind leaving the cock rings on the toys, so I don't have to fumble around so much to get everything set up. I have my eye on a set of TPE cock rings, which would allow me to put a ring on each toy without breaking the bank.

My question is, will the TPE or TPR cock rings react with the silicone toys? Or should I just save up and buy a bunch of silicone cock rings?
