BioWare took this game as an opportunity to really lay out their politics on the matters of sexuality and sexual relations. To anyone familiar with the company and their left-leaning attitudes it's no surprise. Same-sex relationships in Thedas are common and barely worth batting an eye about. In fact there's even a codex treatise on the topic should you wish further reading. Additionally, this is the first game from them that I'm aware of that features a transgendered NPC.
