In response to a discussion I had on this board, I wanted to present a brief fact sheet regarding penis size. I think it's so easy for us to overestimate what an average penis is. Alot of us did not grow up being naked around other men (IE the locker room) so unless we have had a lot of sexual experience with males, we might not know what penis sizes are the most realistic. Now, none of this is about preference because when you buy a sexual prosthetic you might want the biggest your partner can handle. Thats a different story. Knowing the facts may help you with picking out your packer and eventually even assist you if you decide to have surgery.

Penis girth The avereage penis girth is between 4.9 and 5.1 inches.
It is interesting to note that women report enjoying more girth as oppose to more length. The vagina can only lengthen a limited amount to accomodate a penis, and while there are exceptions, most women find it painful for a penis to hit her cervix repeatedly. On the other hand, the vagina has more capacity for girth.
foot size /hand size/ height There is no definitive correlation between heigh foot or hand size and the penis. There is also no correlation between flaccide size and erect size.
Black Guys The stereotype that black guys are more well endowed than white guys is somewhat true. The kinsey study concluded that black men where on average 1/10th of an inch (2.5mm) longer than white guys. The difference may be minor, but it does exist.
Other things to keep in mind
You have to be really careful when researching online. Many websites will flat out lie about the average in an attempt to sell some sort of penis enhancing bs.
The testicles actually make up most of the bulk of a guys 'bulge'.
