Condoms provide by far the best protection against sexually transmitted infections (STIs), but they still don’t provide 100% protection. Even if you always use a condom, it may be a good idea to get tested for STIs.
There are different STIs and they can affect you in different ways. Untreated STIs have a negative impact on the body, sometimes without the person noticing. If you have an STI it could also increase your susceptibility to other STIs and HIV. So it’s a good idea to get tested regularly, even if you don’t have any signs or symptoms of an infection. By getting tested, you take control of your own health.
