And I just can't imagine that homosexuality is something that's even remotely considered amongst Klingon men.
Oh I don't know about that, the Spartans, the Zande, the Samurai, were all warrior cultures that openly included homosexuality.
Imagining a bird of prey on a long extended patrol, mostly male crew, close quarters, sweaty, unwashed, eating raw meat, clad in leather.
