I think I want to do an updated version on who I think is gay:
2PM:
I'm a little suspicious of Jun. K now, given previous conversations in this thread.
GOT7:
Junior, I feel very strongly that he's gay.
I'm suspicious of Mark but it's not very strong, to be honest.
DBSK/JYJ:
Jaejoong- well, I'll eat all of Super Junior's cross dressing wigs if he isn't gay.
Yunho, I feel very strongly he's gay and that YunJae was real.
SHINee-
I'm very convinced Jonghyun and Key are gay and were once in a relationship.
Super Junior:
Heechul speaks for himself (i.e., I think he's gay).
I'm a bit suspicious of Donghae and Eunhyuk but I'm not fully convinced.
For some reason, I get slight vibes with Kangin.
BEAST:
I get low vibes from Gikwang. They were stronger before but not so strong right now.
EXO:
I'm pretty convinced Sehun is gay and I just can't read Baekhyun, for the most part.
iKON:
I can't not think Jinhwan is gay, but the vibe isn't strong though. I get vibes from Hanbin as well.
Infinite:
Woohyun, Myungsoo and Sungjong give me very, very strong vibes.
Bigbang:
TOP is almost undeniable to me. I have a very hard time not thinking he's gay. I don't think about GD a lot, but I would think he's gay too, as I believe GTOP was a thing before. I get low vibes from Seungri.
VIXX:
Hongbin strikes me as gay, but I don't really have any evidence to support it. I just get vibes.
