Sexual Health & Testing

Following guidance for a mandatory “stay home” order issued by county public health officials across the Bay Area on 3/16/20, one San Francisco AIDS Foundation (SFAF) site has been closed and most services have been put on hold. The order goes into effect as of midnight on Tuesday, March 17 and is effective until May 3, 2020, or until it is extended.

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.
