Of course it has no place in the fluff, especially if it's homosexual
And actually the idea of homosexual male still being a male, virile and everything, and specially in the army, is very disturbing to most people, specially military.
However, while the military world tend to be quite homophobic (necessary machismo), statistics anonymously gathered in confined "male only" space (navy, specially submariner) tend to show a different picture. And there is no reason to suppose that homosexuals would be less efficient as military people.
I must admit I suspected I might derange quite a few people by speaking seriously about homosexuality in the military, but actually this is quite on topic. I am not implying homosexuality of anyone here, military or not, but then again, if you take what I was saying as an offence, *You* might look homophobic to me.
You don't have to clarify your sexual preferences Legion 4, I don't remember implying anything about American veterans in my previous post
I merely stated that homosexuality was probably no rarer in army than in the civilian population, and as until very recently it was a mono-genre organization, possibly more frequent.
Specially, as, as you said, testosterone is the stuff of aggression AND the stuff of libido.
Anyone who would maintain that homosexuality doesn't exist in armies would be just as credible as Mahmoud Ahmadinejad when he maintain that it doesn't exist in Iran. I believe the current statistic is something like 1 or 2% of the population. Those would be the people actually realising their homosexuality. In any group larger than a few hundreds of people, say a thousand, it would be preposterous to suppose that "homosexuality doesn't exist here".
I don't think GW would ever want to imply anything such as this, even if they had a joke long time ago when the intended public was adult and the joke restricted to people at least a little versed in poetry. It is not a subject that usually pass easily with people collecting toy soldier in general. But SPECIALLY because sex is a taboo thing when speaking about games, and homosexuality a taboo thing when speaking about soldiers, I like to envision marines, when they have romances, to have romances with other marines.
Specially as male friendship, and the customs and gesture of it in the middle age, particularly among knights and monks - both archetypes inspiring the SM archetype in GW universe - was sometime quite ambiguous or even borderline compared to the vision we have of it now.
The idea of Uriel Ventris and Pasanius as lovers (possibly platonic) does come really easily to the mind, for example. At least for me, but I realise I might not think of such things in the way most of us toy-soldier collecting people do
See here we go again, more holes and silliness in the GW 40K fluff ... What makes most males good soldiers at the seminal level is testosterone at high levels especially experienced at younger ages (about 16-25 year of age). Now I'd think bio-genetically engineered soldiers, like G/W's SMs are supposed to be, would or could be "alterted" to fit the needs of the Imperial Gov't ... Now that being said, at one point way back when, the Space Wolves all had Latin names, they sounded more like Romans than Norse. Then later the fluff even hinted that they were Werewolves ? The Dark Angels were all supposed to be American Indian types ... Even the the Blood Angels were alluded to as being Vampires ? So now they are all gay with the Dark Angels in the lead ... Please ... typical of G/W playing Orwellian New Speak with the fluff ... So are the Space Wolves gay werewolves and the Blood Angels gay Vampires ? Indeed ... more G/W silliness. Really has nothing to do with the game and like much of the fluff I dismiss it. When the ever changing G/W staff writes up this stuff, I have to think again, that none ever served in the military. And really know nothing about being a real Soldier. Now I never heard of the "Gay Johnson" poem ... And really don't think it matters ... But whatever motivated the though that, along with all the other silliness ... Werewolves, Vampires now gay ? May be someone there has some latent homosexual issues ? Or is making some statement on gays ? I really don't care ... it has nothing to do with the game. Just continues to confirms my thought that the G/W fluff is just plain convoluted, silly and fickle ... I'd think that if SM's & SoBs got together there would be "a Rumble in the Jungle", "Lust in the Dust", etc., etc. ... And what 2 or more consenting adults do behind closed doors, is their own business ... and it certainly has no place in the game or fluff for that matter, in my mind ... And I'll freely admit I think the Werewolf/Vampire thing is less silly that the Gay thing. And I'm not sorry to say that I like girls/women/females and always have. 
Call me "Old School" ! 
Whatever !!
