I know my SuJu oppas love to do stuff that make people doubt their ual orientation. They don't mind crossdressing or kissing eachother. And most of them are pretty feminine. (I don't mind though, I have a thing for feminine guys. LOL! That explains why my bias is Ryeowook)
But seriously with all due respect to gay people, I don't think anyone in SuJu is gay. Not even Heenim. ^^

i think heechul can be gay

i think its heechul!!(he kissed nearly all suju members!!)but if he truly was i still dont care ( to be honest i'd like it more if he was!!) because i love him no matter what!!<3
