In spending a fair amount of time in the Middle East and North Africa, I've been witness to a lot of what's called "homosocial" culture.
Despite variable views on homosexuality, Islamic countries maintain extremely friendly, touchy-feely contact between men. When walking the streets of say, Marrakesh or Cairo, it's common to see men touching each other's thighs in all-male cafes, and holding hands as they walk through busy souks.
Homosociality, which is defined as same-sex relationships that are not of romantic or sexual nature (such as friendships and mentorships), has only really been theorised in the West since the 1970s, but has been present in Islamic culture for centuries.
Though not to the same extent, I've started to notice homosocial communication down here in New Zealand, too.
Case and point: at the weekend I was told by a straight, male, army colleague of my husband's that I was "looking fit", before proceeding to innocently touch my chest to give my muscles a bit of a squeeze. Perhaps this seems strange to civilians, but the military encourages a homosocial culture – I find it common to see male Army officers complimenting each other, hugging, even – when they're drinking – kissing on the cheek.
When your profession is warfare, it's unlikely that you're worried whether people consider you manly enough.
