it has any thing to do with segregation of sexes. The segregation came after the "oil" boom. With bedioun & Arab tribes migrating into Qatar & the adaption of "wahabism".
Homosexuality was there way before that.There has always been the "others".
Folk/wedding singers back then were all men. That have remained up to the mid 80's & ended up in a witch hunt. Where all had their head shaved & forced into the army!
