If you are aware you have a sexually transmitted disease, you should use condoms on your sex toys if you intend to have sexual activity with your partner. Extra precaution should be taken, such as placing a fresh condom when moving the toy from the anus to the vagina as there are serious bacteria that can cause infections in the vagina. The risk for acquiring a sexually infected disease through the use of sex toys is even higher if one of the persons has a sore or wound which is touched by the unsterilized sex toy. Using a fresh condom for sex that involves toys with a new partner also helps reduce your chances for getting infected.
Body secretions touch sex toys which are why they can transmit STD’s, and the bacteria can linger on these toys for a long period of time. Bacteria can come from sores, wounds, and bodily liquids such as mucus and even blood carry disease around, which is why sex toys should be rinsed properly after and before use.
Soaking sex toys in hydrogen peroxide for 15 minutes is one way of efficiently disinfecting them before use and for storage.
