Gayspeak: 성적지향 (Sexual Orientation)

Here is a very important word for the Korean queer community.

 성적지향 (seong-jeok-ji-hyang)

Obviously, this is more of an academic word ... you wouldn't go up to someone and ask what their sexual orientation is. 
야! 조권아! 성적지향 뭐야??
This might be seen in the news. For example, this news article is titled '성적지향 담론 확장은 차별금지법의 기초', which translates to 'The Extension of Discussing Individual's Sexual Orientation is the Basis for Non-Discrimination Laws'.
