Okay so I found this old Jaejoong interview on http://ich1heavens.tumblr.com/post/48153876118/kim-jaejoong-100-questions-100-answers and they ask two times about gay relationships. I have never read this before so I was really surprised and it was before he debuted.
So the questions were:
26. Do you think gay relationship is acceptable?
- Gay is also a man, isn’t he? ㅡㅡ;;haha (TN: here, he wrote “아닌가?†a word used when someone asks question or doubts himself)
55. What do you think of love relationship between gays?
-Gays are also humans so that’s why they love each other
