on eras, it asks you if you're couples matching, and the name of the person you are couples matching with, and the specialties he or she are applying for. you want them to know who you are couples matching with- if someone really wants you, or wants her, they may be able to chat with a PD from the other person's program to get one of you an interview or move you up higher on the ROL. it shouldnt matter that you are gay- you dont have to be a "couple" to couples match. you can couples match with your best friend, your sibling, a classmate who you plan on going into practice with later ... it doesnt matter. there are a set of twins in my class that were gonna couples match. if you're hesitant to announce to a program that you're gay, (and if anyone asks about the person you are matching with- they may not even ask or care), just say you guys are close friends and want to be in the same city. no big deal.
