I have a set of dilators (not sex toys so much as sex.. uh... well, lets put it this way, my physical therapist gave them to me to use to make sex hurt less.. So they're not exactly toys, since i"m supposed to just lie there with them in me for 10 minutes every day...) and my PT's words were: "Sex is not sterile. These don't need to be sterile. Just warm water and soap. You can even put them in the dish washer."
