Hi Boris,
I have no idea if the guy shown is gay or not, and to be honest, where and how someone lays the pipe is not my business.... and I dont see how you can see that on the photo?
I posted this because this guy looks like a full on disco Gigolo. And if you google the Spanish Foreign legion... this dude is not exactly the average Legionnaire? His pants that bit tighter, his gold chain, and he spends more time on his beard than the average guy does in the bathroon in a week.
I think most Sgts would kick a soldiers ass if he came onto parade wearing a gold chain like Mr-T, and most Sgts would say "You a Gigolo?? Shave that beard off!"
