I heard something about it correlating to how monogamous an animal species is, and I think length in time of copulation has some influence.

>>10221068
Presence of OP's mother is correlated with smaller penis length in the given race

Testosterone is the primary factor behind penis growth during adolescence iirc.

Asians have exposed themselves to a lot more phytoestrogens than the other races over time.

Africans haven't really had enough wars of the type where all their most violent men get killed. Rather quite the oposite is taking place there. As a result they probably have males with higher testosterone levels.

>There is a close correlation between testicle and penis size and promiscuous social strutures in our primate relatives. Gorillas, living in harem social structures, retain a diminuitive penis and testicle size. If you are a male and operate in a promiscuous social structure, producing large quantities of sperm through a delivery system likely to sucessfully distribute those sperm (Margulis & Sagan, 1991), for example in chimpanzees, this gives you a decided advantage over other males. If you are a male living in a heirarchially organized social system, a gorilla harem for example, then copious amount of sperm production or a long penis does not increase your chances of producing progeny. Your ability to prevent other males from sexual contact with females, by force or intimidation, positively influences your chances of reproductive sucess. Human males evidence sexual anatomical characteristics suggestive of a promiscous social structure (Wilson & Daley, 1992). There are exceptions. These are those human males living under highly hierarchial patriarchal monogamous social structures for thousands of years (Miller, 1994).
>Though Darwin hesitated to pursue the implications, human evolution may have unfolded following the dynamic that comes with the benefits of female choice. Trivers (1985) notes that female choice tends to reinforce certain characteristics in the male population. Tanner (1981) applies this principle to human evolution and comes up with a compelling argument that with big headed babies requiring years of care, males disposed to making sure that the children are taken care of would be selected by the females as copulation partners. Human anatomy evidences this suggestion. A large penis and big testicles suggests a non hierarchial promiscous social structure, usually characterized by female sexual selection.

is onions consumption associated with small dicks?

Black women have thicc thighs and phat asses. it's a lot easier to plow that shit with a big dick.

>>10221068
Source for that graph? I've seen somewhat lower estimates for Whites.

Didn't the cold environment contribute? Weren't men with larger and more exposed genitals more likely to freeze to death?

Also, didn't African tribes value penis size? Women would judge men based on the size of their penis to see if they would marry them?

>longer penises are more effective at removing semen
the answer is rape, the bigger your dick is the more likely it is that youre ancestry is filled with rape babies, although this ignores civilized society.

>>10221851
>Didn't the cold environment contribute?
This.

>>10221883
Yeah, plus baseball

>>10221108
PJW?

Whites have the biggest dicks. All who say otherwise are cucks that rely on self-reported and inaccurate data.

>>10221934

>>10221937
All the white dicks I sucked were larger than the black ones. How's that for self-reported data?

>>10221111
So asians are gorillas and blacks are cucks with STDs

>Intensified sexual selection of men
>If some men have more wives, others will have to do without. In general, men will have to compete more keenly with each other for access to women. When such rivalry intensifies in non-human species, the result is an intensification of sexual selection for larger, stronger, and more muscular males. This may explain why the highly polygynous, agricultural peoples of sub-Saharan Africa are so physically robust.

>>10221954
>agricultural peoples of sub-Saharan Africa are so physically robust
Most of them are scrawny manlets though. The only "physically robust" blacks are the former slaves with 30% white ancestry.

Neanderthals and Denisovans' hybridization.

>>10221972
the malnourished ones are manlets.

How do you measure penis size anyway? Top or bottom measurements; point to point or arc-length, erect of flaccid?

>>10221068
How do you measure penis size anyway? Top or bottom measurements; point to point or arc-length; erect or flaccid?

The reason has to do with ease of mating

White and asian women don't have baboon asses requiring 10 inch nigger dicks to get through.

>>10224624
There's also bone-pressed vs measuring to the skin.
>erect or flaccid?
The graph in the OP is supposed to be erect. It's what everyone cares about because you can't do much with it flaccid.

>>10221108

In 253 Tanzanian males 10 to 47 years old mean ± SD penile length in adults was 11.5 ± 1.6 cm, mean shaft circumference was 8.7 ± 0.9 cm and mean glans circumference was 8.8 ± 0.9 cm. As expected, given the variability of puberty, measurements in younger males varied significantly. Glans circumference highly correlated with height (r = 0.80) and weight (r = 0.81, each p <0.001). Stretched foreskin diameter moderately correlated with height (r = 0.68) and weight (r = 0.71, each p <0.001).

Is your source in your own pants?

>>10225123
yep, I have a tiny white penis and I tried to fuck a black chick with a huge ass. I could only get like 2 inches of my dick in her pussy.

>>10221068
There are no genetic differences in penis size. Its all cultural.

One of my buddies works in the porn industry as a producer. He says it's almost impossible to find white guys that are as big as the black guys in porn.

For every huge white guy like Danny D, there are least 20 or 30 black guys that are just as big or bigger (Lexington Steele, Rico Strong, Shane Diesel, Mandingo, Rob Piper, etc.)

>>10227711
Wow. Lisa Ann is truly a champ if she got gangbanged by all those huge black cocks.

I don't think the average woman would be able to survive that.

This thread triggered my PTSD. There were two black guys at the gym I go to. In the locker room, we were changing our clothes and you couldn't help but notice the huge horse cocks on those black guys. There was a stark contrast between them and my tiny little white peepee.

>>10227711
>Thousands of active male porn stars
>at least 20 to 30 black guys
>Names 5

The list is so small it's about which statistical outliers want the job at any given time

People like Jonah Falcon could do porn but there's no reason to. Eventually you're just so high on the sexual marketplace, sex is on a revolving door so why bother with the industry.

>>10228277
>Thousands of active male porn stars
Incorrect. At least not in straight porn.

I know the business a lot more than you and I can say confidently, there aren't even 100 active male pornstars in the US and European industries combined.

Sounds feasible but that would mean caucasians would have a smaller penis than asians.
The caucasian race was forged in ice and snow.

>>10227711
Don't forget Dredd. That dude has a monstrous big black cock. There was a video of him wrapping a wrist watch around his shaft. The girth is just jaw-dropping.

I'm surprised he's able to fuck women without tearing them in half.

>>10229627
Dredd makes every wh*te "man" shiver. But at the same time, those same wh*te guys probably have fantasies of that huge BBC plowing their wives or girlfriends.

>>10221068

Which doesn't increase the likelyhood that your information is correct, at all

> there aren't even 100 active male pornstars in the US and European industries combined.

IAFD started in 1981 and has data on 115,000 adult performers. Around 30% are male, represented by around 34,500 males. I retract my estimate that there are "thousands of active male porn stars. But less than 100 is extremely low ball.

>>10232098

vast majority of them are gay porn actors though

I'd rather have a longer flaccid penis though, erect is whatever

Post girth pls.

>Africans haven't really had enough wars of the type where all their most violent men get killed.
Considering all the wars going on there I sure wonder what kind of war it would take to fulfill that hypothesis.

no it wasn't. Mongoloids are from Lake Baikal in Siberia, Caucasoids are from the Caucasus and Western Eurasian steppe which is nowhere near as harsh as eastern Siberia
>>10227624
this. oppression makes your penis bigger.

>>10227711
I don't know if my comment is worth anything but I'm gay and I had sex with lots of guys and I observed that there is no correlation between height and penis size, the one with the biggest dick (10 inches measured) was 5'6 tall, he was an spic, another guy was 6'2 and white, his penis was 5 inches, on my experience taller, white guys have smaller or average dicks and blacks/spics have bigger ones, when the dicks of spics are not that big, they tend to have a good girth.

I use my own dick to compare and measure, since it's 21cm long.

Also I have been with 130+ people.

Whites are smaller than most other races.
