Homosocial behavior among Muslim men?

[carmarthen]

There was a brief article in Psychology Today about platonic affection between men in Muslim countries that might be perceived as romantic in Anglo-Christian countries (e.g. hand-holding, hugging, exchanging of flowers and poetry), but I don't really think of PT as being a pinnacle of scholarly accuracy, so I would like to find out more about these behaviors if they are indeed common.

I tried searching for

physical affection muslim men
homosocial muslim men

and mostly came up with information about the prohibitions of various interactions between men and women.

Can anyone recommend some good sources about this? I'd be really, really interested if anyone knows of any dealing with 19th-century Iran in particular.

Thanks in advance!
