As to “needing” sex several times a day, do they “need” it even once? The terms used do not describe what goes on. It is not a matter of “need” unless you consider breating a “need”, or hunger or thirst a “need”. The sex drive for the male of every mamilian species is on the same level as hunger, thirst etc. It is basic, it is what drives them.
It is all part of what makes them men, the hunter, the protector etc. It is not what they want to be, it is what they ARE. And if you call what you want, need, then yes they do need it 3 times a day and more if they have they physical endurance for it. It is not their choice. In the article the man said that men being faithful to one wife is a huge sacrifice. That is true, it goes totally against his nature.
Sorry, I understand men to be every bit as human, intelligent, spiritual, and civilized as women. Our minds are what separate us from the animals.
Moreover, as a believer, I understand us all to be made in the image of G_d. Faithfulness and self-control are more a part of our nature than wantonness.
The illustration that there is a sub-culture from Mexico that “needs” sex more often than the rest of the nation or from men in the US, is illustrative of the role that cultural conditioning plays.
