But this line IS PRICELESS:
This is not the first time Greeks have been angered by suggestions Alexander was homosexual and had affairs with young men.
There is hearsay evidence that Alexander and Hephaistion payed homage at the graves of Achilies and Patroklos, Alexander to Achilies and Hephaistion to Patroklos. But that's it. Nothing else. Nada. Ziltch.

On top of that, according to Arian, one of Alexander's leutenants offered to send him an attractive butt boy captive. Alexander reportedly reacted in disgust and said he never partakes of such vices.
So there you have it. Was Alexander gay? No. Was he bi? Maybe, but we really can't tell.
