The two guys could be either. If they are just interested in Kissing, and being "Bros", then they are most likely just Queer. If they want more, then they are more likely to consider themselves Gay.
Queer, in modern terms, is more the same as Metrosexual, except they do express some interest in the same sex. There is an attraction, but it is limited in scope.
Twenty or so years ago, the terms were more interchangeable. In the 90's, Queer was more an expression for anyone outside of the main stream. It was typically recognized in the same way that LGBT is now. The problem arose, when some began to believe that it was a negative label, referring back to the older meaning of "odd", "different", or more often "insane". This was partly due to the association with HIV/AIDS that was occurring at the time.
If I am following correctly, in the later part of the 00's, the new generation reclaimed the term, and rebranded it. So over the last 5 to 10 years, it has once again become a term for the border. It also over the last couple of years has come to be more associated with the Gender Fluid movement, though where that will lead is anyone's guess.
