Don't be too serious with this folks It's a fun poll...
First let's baseline - most experts agree that an average human male's erect penis length is between 6.2 to 6.4 inches long, and approximately 5.0 inches in circumference (that's 161 mm and 127 mm respectively for metric users).
After a discussion with my significant other a comment was made that "average" is best, and while that was flattering and though it was a "nice" thing to say at the time, I thought it wasn't totally honest. I would suggest that most men, no matter their size would gladly be larger - in fact, many would sell their souls to have to roll it up or be forced to strap it to their legs. Women on the other hand, as the cliché goes - says size doesn't matter but my argument is this:
Biologically (of which I know little about Biology), men and women are attracted to each other by a set of genetic universal virtues. We are attracted to each other not only chemically but by symmetry of their faces, locations of eyes, nose, mouth, teeth. Length of necks, bust sizes, shapes of our butts, women's hips (larger for child rearing). Women are attracted to men who have broad shoulders, strong necks, chiselled facial features, muscular and athletic for not only protection but for their ability to hunt/fish/provide.
Granted, modern society/culture has skewed these ingrained traits, however I say these things are still there and as we see in animals for example; the largest elk with the biggest rack of antlers wins the right to mate. This is the same in humans and I say the large well developed man, with the largest penis in this case, will win the most women and the right to mate more often. Granted we humans are by and large monogamous - this has caused women to adopt and believe that "average is good" and while physically too large of a penis can be painful, and too small not enjoyable... there is an average range between 5.5 and 7.5 that seems to be the sweet spot.
Cut to the chase section:
So here it is...
Is average honestly right where women want their men? Men, given the choice (hypothetically) is average just right or if there was a sure-fire guaranteed option, or wouldn't you like another bit? And yes, this is always a "man" thing - so obsessed with size and doubt of our performance or abilities, but what man hasn't had at some point in their life doubts? Women have self confidence problems about everything - can't men have just one self confidence issue?
