Most STI’s are transmitted through bodily fluid to bodily membrane contact, which also means most can be transmitted through oral sex. STI stands for sexually transmitted infections, which are the same as STD’s, but “infections” helps imply treatability. 
The risk of all STI transmission is even higher if oral sex occurs when someone has open cuts or sores in their mouth. Here's the thing: some STI’s may never show symptoms (yikes!), so the risk for transmission still exists even if you can’t see external signs of an STI. This is why it’s so important to get tested before each new partner. Check out this article for more information about the types of STI's, how they can be transmitted through oral sex, and how to stay protected.

Now that we got all the scary information out of the way, the good news is STI’s are totally preventable! Using some form of barrier like an internal condom, external condom, or dental dam is the only way to protect against STI transmission during sexual contact. What is a dental dam you ask? A dental dam is a thin piece of latex that covers the vagina or anus to help prevent the spread of STI’s. You can order them through CPE’s Bedside Box program!
