An erection is a complex event that requires the interaction of the brain, nerves, hormones, and blood vessels. This process is separate from ejaculation and orgasm, both of which can occur without an erect penis. The male hormone testosterone, which is secreted by the testicles, controls the function of the penis and a man's sex drive. The brain starts the changes that will produce an erection. http://www.buy-viagra-with-us.com/
"We need another and a wiser and perhaps a more mystical concept of animals. Remote from universal nature, and living by complicated artifice, man in civilization surveys the creature through the glass of his knowledge and sees thereby a feather magnified and the whole image in distortion. We patronize them for their incompleteness, for their tragic fate of having taken form so far below ourselves. And therein we err, and greatly err. For the animal shall not be measured by man. In a world older and more complete than ours, they move finished and complete, gifted with extensions of the senses we have lost or never attained, living by voices we shall never hear. They are not brethren, they are not underlings; they are other nations, caught with ourselves in the net of life, fellow prisoners of the splendor and travail of the earth."
--Henry Beston, 1928
