Goran Beviin and Medrit Vasur, Mandalorians, were a gay couple, but that is it. And even then it was very subtle; the words "gay" or "homosexual" or "husband" were never used. Vasur was called Beviin's "partner" and Vasur made a joke about how Boba had a hot wife, but he couldn't tell because he was "no expert." Edit: Oh, I forgot a few SWTOR characters, but it's a Bioware game so it's not really a shock. It would certainly be silly to make Luke Skywalker gay. Especially since he was established to be in love with Leia (before he knew she was his sister) and, in EU, had multiple relationships with women, marrying Mara Jade. It would be like announcing that Captain America was going to be gay in Avengers 2.
