I have always been relaxed with my friends. I think it has more to do with the fear of being called gay by others, and how 1D and this new bunch of boybands changed that vision.
Personally, I have always been comfortable with myself and around my mates, and being caled gay doesn't phase me as my gay friend is one of if not the balsier of us all, so I don't take it as an insult.
straight guys have always done that....straight women do it too
it's' nice to see more straight boys playing around in the way women do without having to fear being labeled as gay
