Anyone (straight, trans, or LGBQ) who has oral, vaginal, or anal sex with or without a condom may be at risk of STIs and should discuss with a medical provider what frequency to be tested.  If you are a bisexual or gay man who has multiple sex partners, you should get tested every three months. Anyone who shares injecting drug equipment should get tested at least once a year.  If you have been told by a sexual partner that they have tested positive for an STI, you should get tested.
