If I had a sexually transmitted infection, I’d know it because I would have symptoms.
False. Symptoms of a sexually transmitted infection (STI) are not always obvious, and they may not even be present. In fact, in men, some STIs are actually asymptomatic more often than they are symptomatic. For example, Chlamydia and gonorrhea in the throat rarely if ever cause symptoms such as sore throat. Even in the rectum, Chlamydia and gonorrhea only cause symptoms about 15-30% of the time. This is why it’s important to get tested regularly in case you have an STI without knowing it.
