What are STIs?
Sexually Transmitted Infections (STIs) are passed from person to person during sex.
An older term for STIs is STDs, or sexually transmitted diseases.
Sex is putting the penis into the vagina, rectum, or mouth; and/or putting the mouth on the penis, vagina, or rectum.
You cannot get STIs through casual contact.
If you think you have an STI or that you have been exposed to an STI, STOP having sex immediately until you are tested and/or treated by a healthcare provider. You can order a collection kit on this website to be tested for chlamydia, gonorrhea, and trichomonas. If you have an STI, you are at increased risk for getting HIV (Human Immunodeficiency Virus) - the virus that causes AIDS - if you are exposed to that virus.
