Partner communication is a critical part of STI prevention. The most common prevention strategies (abstinence, mutual monogamy, and condoms or other barrier methods) require open communication with sexual partner(s) to be most effective. It is important for partners to be able to discuss their sexual histories, as well as let each other know if they experience any STI symptoms to allow them to get tested and treated if necessary. Open, honest communication on this topic can be difficult, but some communication is better than none at all; for example, some people find non-verbal communication, such as putting a condom on the pillow rather than talking about it, easier.
