These include the exclusively gay male romance with Steve Cortez, the lesbian romance with Samantha Traynor, and the expansion of established character Kaidan Alenko into a bisexual option available to male Shepard, a change from his prior limitation to female Shepard in earlier games. Liara T'Soni remains available to either gender as an Asari character.

These mechanics elevate queer relationships from optional side content to integrated narrative elements. Creator intent drove the inclusion, with BioWare statements emphasizing diversity and inclusivity in character creation. The queer content was added intentionally amid prior series backlash and player demand, as confirmed by producer Casey Hudson and writers such as Ann Lemay, who also highlighted efforts around diverse female characters including the first female Turian Nyreen Kandros in the Omega DLC. This positions thematic elements of identity and representation as foundational to the game's design choices rather than incidental.
