CDC recommends gay and bi men with multiple partners get tested for STDs and HIV every three to six months. Depending on the number of partners you have, and what kind of sex you’re having, you may just want to schedule a test for yourself every three months.
To get the most complete test possible, it’s recommended that each body part you’re using in sex get tested. If you are having oral sex, ask for a mouth swab. If you are bottoming or being rimmed, ask for an anal swab too. Your genitals are usually tested through your urine.
