I was going through my toy box the other day and pulled out my Rockin' rabbit cock ring, which has not been used in a very long time, and I noticed that it looked like the material was changing colors and had become softer. Does rubber break down over time? I don't know if my toy box had possibly been exposed to high temperatures at some time, I don't think it has except possibly briefly when we moved. Other than that it has always just hung out in my closet. The cock ring was put away clean and I was storing it in a plastic baggy to keep lint from collecting on it. It was already rather tacky/sticky to begin with but now it's super sticky almost gummy feeling. It's really gross. I guess I'll be throwing it away.
