Sexually Transmitted Infections (STIs)
Sexually transmitted infections (STIs) are diseases passed on from one person to another through vaginal, anal or oral sex, as well as through genital contact with an infected partner.
It's possible to have more than one STI at a time and the only way to be sure that you don't have an infection is to be tested.
