About The Book of Nature

The size of the Testes vary in different persons. The average of mankind have them each about the bigness of a pigeon's egg; but sometimes they are larger. It seldom makes any difference in the actual power of procreation whether these organs are large or small, though persons with large Testes can generally perform the act of copulation oftener, and with less exhaustion. A man with large Testes generally has a large Penis, as the size of the one usually governs the growth of the other; but it is by no means certain that sexual connection thereby affords him any more pleasure. Such men should marry with great caution. Many females are incapable of affording them pleasure from the comparative smallness of their private parts; and they suffer much pain and ill health from such intercourse. On the contrary, men whose genital organs are not fully developed, though they may impregnate, yet they cannot always give full satisfaction to the female. If it could so be that people about to marry were properly matched in their private parts.
