The Equator Penis Measuring System (EPMS) is the system that gives an approximation of one's penis size. Generally speaking, the closer you live to the Ecuador, the larger your penis is. For example, Africans and Latin Americans living on the equator will have penises measuring around 11 or 12 inches hard, while the English and Scottish living up north have penises measuring 3 inches flaccid, or up to 5 inches hard. There are also intermediate points. Italians, for example, have penises about 6 inches flaccid, and 8 inches hard.
