The material section says that it is non porous, phthalates free, and anti-bacterial, so why is the safety rating only an 8? I bought this and the g-ki for my birthday and they are arriving today, but I just became worried that I might have a yeast infection or something. I'm so disappointed that I might have to wait to use my new toys, but I don't think it is safe to use them if I have one, right? I don't want to contaminate my toys?
