The infant Jesus was born with 2 inches flaccid. By the time of His Bar Mitzvah his organ approached the length of two fountain pens.

See Flavius Josephus Antiquities Chap 2 ("GLANS PENIS (1a),upturned codpieces and salvation", (1b) Jesus's Haftorah.)

The reference to Jesus in Josephus is considered to be an interpolation.

I was wondering why there is a post here about Jesus - seeing how this is a thread about evolution. It's not like there's any connection between Jesus and evolution. :confused: If somebody wants to post about the Jesus penis, they can post that in the "Celebrity Endowments" section. :rolleyes:

poster "crossy" states in another thread that he has bipolar disorder. I have come across a few of his posts

The reproductive fitness advantage of the glans is likely completely null in most non-poly-amorous societies at this point. In terms of size there's probably a negative advantage in that the genetic and social conditions which would produce abnormally small penises are weeded out over time.

As such, the majority of penis selection throughout the world was probably not done on the basis of size, but rather on the basis of lack of size. Length probably is selected for more in those wherein females had larger behinds (either due to their own genetic predispositions, or due to social conditions, such as the desirability of larger women) because larger female posteriors create an increasing length requirement in order to successfully copulate.

This makes substantial sense when looking at regions historically; European nations which were heavily influenced by the renaissance ideal woman typically have larger penis sizes. Those cultures which typically had slender women (especially those which have had little outside interference, such as japan and korea) tend to display smaller average lengths.

This, however, is only part of the picture, because beyond one's genetic size predisposition, many people who do not grow optimally will not actually reach said size. Areas which had increased instances of incomplete growth would again have a larger selection bias against a makeup which would produce smaller penises.

That said, it doesn't seem that marker genes which can be mapped in order to confirm the various theories have been discovered, so everything in this thread will probably remain at some level of enlightened theory because of the lack of evidence.

There doesnt seem to be a strong selective pressure for a larger than average penis these days. Women are more interested in having children with a man who is financially stable and a good provider / wont leave them on their own with a baby, according to anthropological studies.

Of course, you can argue that "larger than average" penis sizes are a recent evolutionary step for mankind, however, I would argue that it's just the spread of wealth, technology, and other things that have enticed those "big guys" hiding out there to come out and enjoy the freedom.

I suspect that the belief that there are more large penii now may be related to us having better digital cameras and faster internet speeds than they had at any other time in the last two millenia.

Large penis is a product of pornography. Men no longer show truly flaccid penis anymore and always fluff it up before being naked. You'll notice in porn that very few actors will pull down underwear before having had hand inside playing with their cock long enough to no longer have a flaccid penis.

And yes, as nutrition/health improves during childhood/puberty, men grow taller and thus have longer penis. But what we see in porn does not reflect the reality. You get much better reality in locker room showers.

Better nutrition & health improves make the diference, men grow taller and with biger penis. In modern life sex become more important.
I think that under the preshion of pornography & internet (is full with discutions about penis size and the most freqven conclusion is bigger is better), and a lot of advertising for penis elargement will go to make men & women more costient about the size, this will go to a new fashion how say ''bigger is better'', like muscles for man and siluet for woman, and a lot of man and woman go to bodybuilding and fitness so a lot of man will tray to enlarge their penis and women ( how became more independent in modern society) will be more interested to have sex with mens how have big cock.
I know a lot of young guys how practice penis elargemen, and i see parents become more carfuly about the development of their sons (like our parents with grow taller).
I think in 50 years average penis size will be 1 or 2 inch bigger than now. More changes than 5000 years of natural selection and evolution.

There have always been big cocks, but until recently we haven't had the means to view them erect, or measure and collate worldwide statistics. It is possible that better nutition could lead to larger cocks, but it seems that the real correlation is adolescent testosterone levels, which is genetic rather than environmental.

Recently, two compressed evolutionary traits have been noticed. Until recently, African women were typically shortish and stocky, because that's how African men like their women. Over recent years, the European build (tall, slim, long-legged) has been available via magazines, films and the like. And it has been noted that the latest generations of women in Africa are taller, slimmer and longer-legged than previously.

The other trait is also to do with women, but this time white women. Women's attractiveness has changed dramatically over the last 100 years or so, or even more recently than that. Men have not improved in the handsomeness score, however. We now have many images of attractive women, compared to past times. If you look at pictures taken of women, say, in the late nineteenth and early twentieth centuries, you will see a lot who are rather 'plain'. Look around the streets today, and omitting those who are overweight and obese, how many plain women do we see? Not many.

Evolution is often thought to be slow and steady and incremental, but that isn't always the case.

Very true! You hardly see a real flaccid penis in porn anymore. Porn has a lot of men believing that these semi-erect cocks are in a true flaccid state. They are not! By the time a stud shows his dick, his dick is already filling up with blood.:biggrin1:

It's definitely a new thing. There is a documentary called The Anatomy of Sex. It explains that when humans began to stand upright, they began having sex facing each other. Because of the position of the vagina only longer penises could penetrate deep enough to have a good chance at reproduction. Through natural selection the smaller penises kept getting weeded out until pretty much all remaining genes were those of larger penises being passed down. They have continued to get larger until now and I'm sure they will continue in the future.


Check it out if you get a chance. It's an interesting watch.

This is ridiculous. Penis size doesn't correlate at all with survival or anything of that matter. Look at alligators; in the past few years their penis size has actually decreased. Most, if not all animals, have indicators other than organ size, that shows a good mate. And it's like that with humans. Women might want to have fun with a big cock, but usually if the woman is responsible and the hung stud isn't, she'll hopefully see that and settle on a much more mature, settled man. Whether that man has a big dick or not is just a plus.

Everyone here is so obsessed with size that I really wonder if alot of you in real life have other issues. Do you all constantly obsess over it? If that's what makes your life, and let's you sleep at night, that's fine. But I'm going out on a limb here and classifying those that do with BDD. Evolution is about the strongest genes surviving. Will a big dick protect you in society? Probably not. Would athleticism and intelligence? Yes. Those are the things being passed down, not really dick size. Intelligence and athleticism isn't exactly inherited, but the pre-cursors for it are there. And anyway, I figure dick size to be 80% genetic, 20% environment ~~. Although I'm sure HGH will change all that, and soon kids will be walking around in diapers with fully grown, adult dicks, but if that's where our future lies then I'm going to be one very depressed individual.

You guys ever read Next by Michael Crichton? It reminds me of this. The big dick gene? More like testosterone secretion during puberty. I'm just wondering if we'll ever find a way to reverse it and allow for penis growth AFTER puberty. That is HUGE money for big pharm, so we'll see how this future ends up

If you know anything about genetics you know that most genetic changes actually are bad. A gene gets damaged by cosmic radiation and the kid is born with hypospadias. It also serves to reason that penis size above a certain point proves to be bad. Who would want a foot long dick? if you have to stand up and do with only 6 or 7 inches inserted is it an advantage? There are also some indications that guys with a large glans are more likely to impregnate than those longer or simply with a small diameter because a large head plugs the area in front of the uterus after ejaculation longer and allows thee sperm a platform to end up in the the uterus. So size is relative to what you need in terms of reproduction. Those long skinny tools can do the job but the large pistons are more likely to drive the sperms home.
