Most gay men own one or more sex toys, but we’re pretty shy about talking about them! Because of that, most of us also usually only have hearsay knowledge about what they’re made of, how to take care of them and how to use them.
It doesn’t help that most dildos and butt toys are stamped with a disclaimer that reads "for novelty use only.” This is how manufacturers get away with not including any instructions about their use or care or even listing their ingredients on the label. It’s also how they avoid lawsuits from people who injure themselves from playing with the toys that they make.
Regardless of any brand name or proprietary substance that manufacturers claim to have invented, sex toys are really only made out of three major materials. The first, most popular and cheapest of them is Thermo Plastic Rubber (TPR).
The overwhelming majority (80%) of all packaged sex toys are made of TPR. That’s because it is inexpensive and easily formed into lots of different shapes through injection molding. A secret about TPR that no manufacturers ever tell you is that it only has a shelf life of six to eight years. After that it begins to break down.
