Short answer: yes. If you’re only using it on yourself or you have a long-term monogamous partner, you’re all good. However, if you share a sex toy with another person with a sexually transmitted infection (STI) and use it on yourself, you are at risk of catching an STI. Cleaning, sanitizing, and disinfecting sex toys before and after use can keep dangerous germs and bacteria at bay (see below to learn how.) For additional protection, put a condom on the toy to prevent STI spread when using toys with a new person or a different partner.
