The first barrier to this is getting one woman for one night. Scarcity of sex drives millions of men towards the idea that they have to commit to one, for "life", to get any.
Of course - we don't.
As we raise our game, going through dozens of women of increasing quality, a surprising thought in the shower, or while driving, shoots through our brains - when we finally find the girl who knocks the ball out the park, who we finally choose to mother our kids, will we have to give up promiscuity?
I put it to you - don't give up. We need to reassure our inner cavemen, who still don't know about condoms, that we're populating the world, and doing so with the fittest honeys. So even if you find the widest hips, biggest tits, thickest thighs, greatest familial genes, and the most hypermodel face in ONE woman who you then choose to breed with - maintain the conquest.
What king, in history, gave up adding to his harem even though he had married apparently the greatest women in his kingdom? Why should we?
We shouldn't. Feed your cortex the reassurance you are repopulating the planet, even though you're wearing a condom while inside them.
