Sex was never the problem. Now as it is in most old-timey cultures like the Somali culture, the idea was the no one minded if men had sex, but that of women having sex was horrific to the extent of butchering pussies in our case, etc. Oh, but, you and I can see the oxymoron in that, bc who were they, the inconsequential men, having sex with? Women. Always have been.
Whatever 'freedom' men lose in marriage, they're content to lose it over and over again with a quickness, and they do so happily. Meanwhile, women when they lose a husband, are much more likely opt to have the idea of a husband stay lost to them, and instead live contentedly single lives. They also opt for divorce much more often, even though it comes the immense struggle of raising her children singlehandedly.
The glue of the woman is her biology (her child[ren]) and the glue of the man is the woman, and not necessarily the mother of his biological children, nor any of his biological children for that matter.
That is the objective thread of truth in the running themes we see all around us.
Even in the West, the land of sexual freedom, you will never have 'freedom' from it either, bc you are happily 'unfree'. And like I said, sex was never the problem.
