Looks can be deceiving: What is the real story on symptoms and sexually transmitted diseases (STDs)?
A. Most people who have STDs have no symptoms. Someone you know could have gotten an STD, not realized it, and could be spreading it if he or she has unprotected sex. Sometimes the only way to know if you have been infected is to get a test. Some STDs may not yet be detected (seen) even when tested. Since there is probably no way to know for sure if your partner is infected, always use latex condoms or another barrier if you choose to have sex.
