VDH has indeed commented on this aspect of Alexander, on his own website.

Victor’s comments confirm the following large truth about attitudes to male

homosexuality in the ancient world, and in a great many other times and

places, too: An easygoing acceptance of men taking their masculine sexual

pleasure with girlish men or boys, combined with contempt and loathing for

“the man who plays the part of a woman.” You may say that this attitude

doesn’t make much logical sense, and you may be right; but as a matter of

historical fact, that is how most people viewed the matter in most times and

places down to the present-day West.
