By using statistics we can describe the variation of sizes in the general population of penises. First, we must determine what really is "average". Studies have determined the average penis length is somewhere between 5 and 6 inches. We will settle for labeling "average" as 5.5 inches. Average circumference is between 4 and 5 inches, so we will settle for laberal average circumference as 4.5 inches. The standard deviation (SD) of penis length is reported to be between 0.5 and 0.8 inch(es). Once again, we will take the middle, and settle for using .65 as the SD for penis length. For circumference there isn't as much data, but what is available shows the SD to be about 0.4 inches. Using these numbers we can say that 68% of the population is between 4.85 and 6.15 inches. 95% are between 4.2 and 6.8 inches. 98% are between 3.55 and 7.45 inches. 1% are smaller than 3.55 inches, and 1% are larger than 7.45 inches. The "one in a million" mark is at 8.6 inches - that is, only 1 in 1,000,000 men will be larger than 8.6 inches, or smaller than 2.4 inches (about 5 SD's from the mean). As for circumference, 68% are between 4.1 and 4.9 inches. 95% are between 3.7 and 5.3 inches; and 98% are between 3.3 and 5.7 inches. 1% are smaller than 3.3 inches, and 1% are larger than 5.7 inches. The "one in a million" mark is at 6.4 inches for the larger, and 2.6 inches for the smaller. The most extreme ends of the spectrum (read LARGEST PENIS IN THE WORLD here) will be about 10 SD's from the mean; about 12 inches in length and about 8.5 inches in circumference. I have a keen interest in penis size, as I, myself, was blessed (cursed?) with a penis approximately 9 inches in length and 5.5 inches in circumference. Every woman I meet (meat?) in the "real world" is VERY VERY VERY impressed with my size, some are even scared, or quit after some amount of sex (or simply BEG me to cum, so they can get my large penis out of them...). Only in chatrooms do I find "women" that claim to have been with guys that were "at least 12 inches" - never in the "casual relationships" I have with women. Also, I look at a lot of porn (hey, I have a lot of time on my hands, OK?), and NEVER have I seen a man larger than 11 inches; Lex Steele and Mandingo come to mind automatically - but I sometimes think they look so much larger due to tricky photography, camera angles, lenses, etc. Sometimes they don't seem much larger than 10 inches... Anyway, this was my first post...!
