two gay guys dont have to be romantic, true. but how many of your female friends do you never glance at there ass or something. and if there butt ugly, more likely than not, there not your friends, just the way most guys are. the problem is that a gay guy can get a hard on for another guy. might be drunk night, who knows? but im sure youve fucked an ugly friend chick on drunk night too. bromance is the same defining character as a father and son bonding experience. to create this you two must connect on a wide level. the only reason its called bromance and not romance is the fact that theres no sexual feelings. so my conclusion is that is is possible in theory, but not practical in todays world.
