My theory on the evolution of penis size. I saw some of this in either Mens Health or Mens Journal. Humans have very large cocks relative to other primates. The natural assumption is that females prefer larger cocked men as partners and as such the penis is getting larger as we evolve. Let me offer a differing theory. I think the human enlarged penis evolved early in modern mans history as a sign stimulus for other males, not females. As man began to walk upright, his cock became more visible to others. Possibly, the larger the penis, the more dominant the male. The more dominant the male the more females with which he was able to copulate. Females to this day are attracted to powerful males. The more females he screwed the more offspring he had and the more his large cock genes were passed down. Also the most powerful primates on earth, the 500 pound gorilla has a 2 inch penis. No one can see his penis, he walks on all fours, and his dominance in his group is strictly due to his strength. Powerful dominant male primates engage in dominance humping, where the dom males will hump smaller weaker males as a sign of their power and place. We even can see a bit of that here on LPSG, where the currency is cock size, there is no doubt that the larger cocked men are prized over smaller men. Small men are not excluded but there is this underlying buzz by both men and women that big cocks rule the site. Project that back 250000 years, and I dont think it has changed. Also look at how much the MEN here praise big dicks. The men here know their place generally and we sort it out by size. Gay men praise and drool over large cocks much more than the women. Both gay and straight men post pictures and videos of internet monsters they have found with a kind of reverence. Women here enjoy looking at the big ones but they dont obsess over it. Men obsess over it here just like I think they did 250000 years ago. We even see here smaller men offering their women to larger men ostensibly to please the woman but more as I think as this weird voyeur thing. YOu don't see women suggesting that their males go fuck virgins so they can watch. Its strictly a male pre occupation with size. However, as man became more civilized, the real currency that exists today that women want to associate with is power. That is what they wanted 250000 years ago, not penis size. Now power is defined not by cock size but by material wealth. Beautiful women flock to powerful men, of that there can be no question. Jack Welch the powerful former head of GE said it best,, money is better than a full head of hair in getting women. And it is far better than being well endowed in getting females. Genghis Khans genes likely still exist today in large numbers because he literally fucked thousands of women in his conquering of Asia and Europe. His power allowed him to fuck all those women. What is power today? It is being gainfully employed for one. The more gainfully employed you are the more likely you are to have access to females. And honestly the more money you have the better looking the females you get to fuck. Hugh Hefner anyone? And today? Economic power is flowing to Asia, especially China and India. I wont talk about penis size cause it is such a hot button, but testicle size is smaller in Asians and larger in Africans. Whites are in the middle. Africans are falling further and further behind the rest of the world in every conceivable measure and they are still subject to severe famine and epidemics like AIDS. In my opinion testicles (and cocks) are getting smaller, not larger as Asians are beginning to acquire power.
