Straight men only love men as much as the society will give them space within the straight space!

Straight men have a strong need to love other men, but they will only do as much as is the social space available for them to do it (they just won't go to the third gender gay space to do it).

And, surprisingly, they even seem to do the impossible by trying to love men in the negative space available in heterosexual societies, where straight is defined as 'heterosexual'. There they love men by pretending with their lovers that they don't have any sexual feelings even for each other, and by hiding and camouflaging their love for each other and never talking about it... but nevertheless doing a lot of those emotional things that two people intensely in love do, but doing it silently, communicating through silence -- their interest, their hurts, and all those big and small things. They don't speak out even when the relationship they so intensely want is about to break and a small word from them can save it. They'd rather just watch in silence than speak out. They just won't cross the limits set up by the society -- in this case the 'heterosexual' society.

While, all the time their heart beats for their male lover, they keep talking only about women and do all kinds of pretenses to prove their heterosexuality, even when they may or may not have any interest in women.
