Sexual Health & Testing
We provide free sexual health services so that you can have the sex you want and be confident about your health. We offer a variety of free services, including HIV & sexually-transmitted infection (STI) testing, at sites across San Francisco. We believe sexual health shouldn’t come with judgement.

Possible HIV exposure?
Post-exposure prophylaxis (PEP) is for people who have potentially been exposed to HIV in the previous 72 hours. PEP is month-long medication treatment that we are able to provide on a limited basis. The sooner you start taking PEP, the better.
