In nature, the main priority of any mammal is survival and procreation. The female mammal is not only the vessel of procreation, she is also responsible for selecting the male that will impregnate her. Science teaches us that her three main factors guide her selection:



1. Survival skills

The female selects the male with the strength and ability to win over the competition. For example, the deer with the biggest antlers or the bull with the biggest horns are better equipped to survive and, as such, are often the leading candidates for impregnating the female.

2. Testicle size

The female has her own biological clock and, therefore, prefers a partner who can impregnate her quickly, preferably on the first try. Although not necessarily true, large testicles are associated with more sperm, and female mammals find this very appealing.

3. Penis size

In the animal world, females recognize that a larger penis can penetrate deeper into the vagina and increase the likelihood of pregnancy.

Since females routinely picked male mammals with the biggest penis and balls, the selected males passed on their "well-endowed" genetic code to their offspring which resulted, over time, in male mammals in a particular region having bigger and bigger penises. There are parallels in human evolutionary history as well.

Of course, when a female regards a penis as "big", that is relative to the size of her vagina. As a result, science has found that, in any particular region, the size of the penis and vagina of the indigenous people are near equal. For example, in Asia, where the indigenous women tend to have smaller vagina sizes, the men also have smaller penis sizes. This is as it should be since a penis that is too big for a particular vagina can be very painful and in extreme cases, require medical attention.

Today, when traveling to different places of the world has become commonplace and few people live in the land of their ancestors, penis size has become even more of an issue. People from different regions quite naturally compare penis size.

This leads to another important point. Based on the above, certainly penis size matters, but fast-forward to the modern world where sophisticated and smart women know it is not the only thing that matters.

Today's women will agree that a man's performance is much more important than his size. Men with small and average size penises can gain solace from the fact that many well-hung men have reputations for being lousy lovers since they rely on the size of their penis too much and don't develop their skills enough.

The above example also teaches us that penis size is purely biological and evolutionary and has nothing to do with one's ability to please a woman (especially now with the widespread popularity of sex positions designed for men with smaller penises).

The bottom-line? Penis size matters, but it is not the only thing that matters. In the final analysis, performance and the size of the woman's vagina are other factors that are equally or even more important than penis size.
