The only pressures on sexuality I know of during the times of the Greeks was to get married and produce a children as you got older. There were restrictions on social interactions between men and women. But that was required because the society had forced men and women together into one society --- especially through marriage, and this meant that in order to maintain their natural freedom and growth, they needed some restrictions in their interaction --- especially when male-female sex, or rather reproduction had already started to be seen as proof of 'manhood'. All the contemporary traditional societies that I have seen or read about, that allow male-male relationships in the form of what the west calls "bisexuality" have just marginally allowed male-male bonds. They are either tolerated behind a social screen or if in some cases allowed openly then only when the person also fulfills his social duty of contributing children to the community (through marriage!). There is absolutely no pressure on men to bond with men. It's just tolerated. And still, I don't know of one so-called 'bisexual' society where men have not favoured male-male bonds or sex over that of male-female bonds, even sex. The Greeks believed that "If god had not made reprouduction only through male-female sex, women were completely redundant for men". The Afghans believed (and so do other macho cultures in Pakistan and India) that "Sex with women is for procreation, while sex with men is for pleasure". The brave Samurai warriors married only because they had to. They never shared an emotional relationship with their wives. Love could only happen with another warrior. See, whether its the Greek society or any other society accepting male-male bonds, the pressure has always been to get married and to produce children. There have never been pressures to have sex with men. If you know better, please enlighten us.
