how big are you?

[cyba]

oh, btw,,,Alfred's stats say 10" or more <5% of men; 45% be 4.75-5.25,,,gots to love dem growth hormones

That leaves 50+% in some other category - 1", 2", 3", 4", 6", 7", 8", 9"..and the bits in between? I suspect 1"-3" is a smallish %.
Kinsey studied around 3.5 thousand white guys, probably Uni students. It's quite a large sample, as samples go, but hardly multicultural, i.e. doesn't account for the possibility of genuine ethnic/genetic size differences. Apparently, Ginsberg, the gay poet was given the job (and doubtless jumped at it) of measuring all these dicks along the top. The average erect length was 6.21" (similar to other more recent studies) which gives reasonable scope for 7+"..and less, though by no means insignificant scope, for 8+", but much less scope for 9" and, especially, 10", etc.
The trouble is, none of the 'studies' are conclusive.
On ethnic differences, the 19th century French Army surgeon and anthropologist, Dr. Jacobus Sutor, "(who) was addicted to measuring cocks for 3 decades and reported his measurements", stated the largest Arab cocks were found to be between 8 and 10 inches and in his survey he detected definite cock size differences on a basis of race. His comments are a hoot -

Regarding blacks, he wrote: "The penis is almost as large when flabby as it is in a state of erection. It is among the Muslim Sudanese that I found the most developed phallus, and notable one of the maximum dimensions, being nearly 12 inches in length by a diameter of 2 1/4 inches. This was a terrific machine, and except for a slight difference in length, was more like the penis of a donkey than that of a man. The unfortunate Negro who possessed this spike could not find a Negress large enough to receive him with pleasure, and he was an object of terror to all the feminine sex." He concluded that the "Sudanese Negro possesses the largest genital organ of all the races of mankind".

and

Arabs showed the largest average size, measuring 7.2 to 7.6 inches in erection--big enough, according to Sutor, to "produce serious mischief in the rectum of any poor wretch who consented to suffer its terrible attacks."

I guess anal sex must have all the rage.
Again, amusing, but conclusive?
One guy writes, recently,

It's a disgrace that medical science has done so little to study penis size and is obsessed with averages, it has basically ignored the penis like a Victorian prude.

Makes sense. This attitude's generalised in western society. We frequently see female full frontals in film and elsewhere but rarely a male. God forbid if you're a flasher (though many regard that as unhealthy and threatening behaviour.)
We know what we know from our own experience.
I noticed (just) during my encounter with an Asian TLB that she used her hand to quickly measure the length of my cock. It was done in a flash. She'd probably compared that, way back, with a more precise measure, a ruler, and over time become pretty adept at figuring what she was dealing with..and have sorted in her own mind a pretty clear impression of who has what. Which isn't to say she wasn't surprised from time to time.
I don't know. I didn't ask.
