Anyone who has unprotected sex can get a sexually transmissible infection (STI) and you can’t tell who has one by how they look.
Safe sex means protecting you and your partner from STIs.
Using a condom is the best way to avoid getting or spreading infections like chlamydia, syphilis, gonorrhoea and HIV.
If you’ve had unprotected sex, visit your doctor or local sexual health clinic and ask about getting tested.
