You need to understand 'context'. I was speaking of the PRIMARY EXPRESSION of intimacy as designed by nature. For heteros' it is intercourse. They have the default option of anal sex. It is rarely exercised by hetero's. Gays have only the default option. Inherently harmful, unhealthy and demeaning.
As far as I know, NO marriage law in the country defines which types and methods of sex that couples must engage in to obtain a marriage license.
Are you suggesting such a thing? And, if so, how would you police every bedroom in the country?
