The purpose of this study is to upgrade an existing relationship education and HIV prevention program. This program is designed for gay, bisexual, queer, and transgender and non-binary people who partner with cisgender men. This means the program is designed for gay, bisexual and queer men, including both cisgender and transgender men. It is also designed for transgender and non-binary people who partner with cisgender men, including both transfeminine and transmasculine people. The investigators aim to test the effectiveness of this updated program among couples and single people. Participants will complete online surveys and get tested for Chlamydia and Gonorrhea. Participants will be tested for urethral and rectal Chlamydia and Gonorrhea. Participants will also complete at-home point-of-care HIV testing, with confirmatory testing for preliminary positive results. They will also participate in our program on relationship education and HIV prevention. Study staff will follow up with participants for up to 2 years. All participants will be randomized into one of two different conditions: the all2GETHER program or no program. Randomized means that it is completely up to chance which condition participants will be put into. Participants have a 50% chance of being assigned to either condition, similar to a coin toss. Participants should expect that they will be in this research study for 2 years. Participation in this study will be done remotely - participants will never need to come into a research lab.
