When the incident became widely known, Attalus, who was a courtier and exercised a good deal of influence with the king, invited Pausanias to dinner, and, filling with vast quantities of unmixed wine, handed his body over to his stablemen to abuse sexually in drunken rape. On sobering up from his intoxication, he [Pausanias] was extremely bitter about the physical abuse he had suffered and accused Attalus before the king. Philip, though incensed at the enormity of Attalus' transgression, was nevertheless unwilling to show his abhorrence because of his kinship with him and his present need of his services [3]. [...]
Accordingly, the king, wishing to appease Pausanias' justified anger at what had been done to him, conferred on him valuable gifts and promoted him to a more honorable position among the bodyguards.

They played pretty rough back then.
In any case, to answer the question - does that sound like "good boy behavior" turning people gay? Seems these guys were scary MoFos to begin with.
So ergo, case dismissed in blaming Christian values for turning people gay.
