Yeah, at my school, both in junior high and high school, if you didn't shower after gym, most guys would rib you for it. Most common comments:

"Rule #1 of puberty: Shower every day."
"What? Afraid we'll see your inch worm?" (Stack of dimes and little friend, emphasizing "little", also accepted.)
"Afraid you'll pop a boner?" (Especially effective when dealing with kids with a reputation for homophobia.)

We have gotten taller. Why can't the penis size grow?

average human height (for both men and women) has increased approximately 1 inch over the last 40 years. if we assume that penis size is somehow related to overall height (which most studies have indicated is clearly not the case), or that it at least increases at a similar rate, an equivalent increase in penis size based on an "average" flaccid size of 3.5" and an average height of approximately 5'8" in 1960 would mean that 2000, with an average height of 5'9", the average flaccid penis would be 3.6". that's an increase of 0.1", or, in the last 20 years, of only 0.05". I very seriously doubt that anyone would notice an increase of 0.05" at a urinal or in a public changing room.

(I disagree with the 3.5" "average" flaccid penis size though--I believe the average size is actually much lower, which would make the increase over time in this scenario even smaller.)

of course, that's just a guess. it's entirely possible that flaccid penis size among teenagers has increased dramatically over the last ten years, leading to a teenage population hauling elephant-sized penises out of their pants when they take a leak. it's also possible that there are talking monkeys living on Venus.

if something like that WERE going on, consider other possible explanations: as I mentioned before, boxer shorts make things hang looser and thus "longer". plus, it's very common for young people to trim or completely remove their pubic hair, leading to a flaccid penis that appears to be longer, but isn't.

you're free to argue that penis size isn't related to overall height (or anything else) and therefore COULD be increasing more rapidly. every time this topic comes up (and it has several times in the past in different forms), people seem to routinely site "nutrition" as the main contributing factor. what exactly are young people eating nowadays that's causing their penises to grow so quickly? and, why isn't it appreciably affecting the size of any of their other body parts? are they tripping over their ball sacks now as well? do they have especially large colons? and most importantly, why weren't people eating it before?

Ineligible said:
"I think it's quite likely that people are developing sooner because of better nutrition. We know that's certainly true for girls."

studies indicate that earlier sexual development in girls isn't linked to "better" nutrition, but exactly the opposite: it appears to be directly related to increased rates of childhood obesity. however, the effect is apparently the opposite for boys: obese boys tend to develop later than those who are of average or lower weight. since it's widely known that on the average children (both boys and girls) are heavier now than they ever have been, it would stand to reason that in general, if anything boys would be developing LATER than ever.

by the way, being taller has obvious advantages from an evolutionary standpoint, but I can't think of a single evolutionary benefit to having a larger penis. of course, i'm not saying that rules out the possibility of the human penis increasing in size over time due to "evolution", but when other aspects of the human physique whose size plays a role in terms of functionality (such as overall height) aren't increasing at a breakneck (or even immediately noticeable) pace, it seems unlikely that a body part whose size is basically insignificant would be growing to such an extent that people would be observing the change in public restrooms. the turtle whose shell evolved over time to allow him to eat leaves higher up on plants and therefore outlive less-evolved turtles who couldn't reach the food didn't concurrently develop immense nostrils and feathers, because he didn't NEED those thing and had no reason to develop them. (i think a lot of people need a refresher course on how evolution actually works.)

btw you have to admit it's a bit ridiculous to discuss this topic on a site whose population includes many people who post blatant exaggerations and made-up stories for their own sexual enjoyment (like "I was in my high school today and all these guys had huge dicks in the changing room and we all jacked off together" or "my penis is 13" long hard, is that big?")

Large Penis -> More confidence -> More sexual partners -> More offspring ?

But anyway I dont know if penis size has a say in offspring I think its more love or happiness etc which is seldom to do with penis size. For instance many Asian (here they're Asian, but Muslim or Hindus actually) have many kids. It's not uncommon for say 4-5, have heard of many with 10+ children. They also don't have the largest penises and it is much less common for them to be very big. I don't see why penis size would change unless someting really drastic or disastrous happened...

Ender, I don't think that the depth of deposit of sperm has anything to do with conception rates. I know a guy that is truly a pencil dick as far a girth is concerned and is barely 4 inches erect. He and his wife have 6 children and yes they are all his because they all look like him. On the other hand mine is 11.5 long when fully erect and I have fathered three children. Thge things that affect conception rates are sperm count and mobility rate as well as fertility of the female and positioning of her uterus.

Exactly. Also, if it has to do with nutrition, of course it's going to be favored by sexual selection.

The other equation I can think of involves multiple male partners, but that would have more effect on the quality of teh ejaculate.

Sexual selection, though, more often means more mates. Remember, the entire concept of selection is one of competition. In much of recent history, sexual selection has been over traits which essentially have no genetic element such as wealth.

If a woman has multiple male partners, the man with the best-quality semen has the obvious advantage; the human glans, especially the "mushroom" type, also seems to "scoop out" other males' sperm.

LeahCat: Just to throw my ten cents in, if penis size was increasing wouldn't you also expect an increase in the average vaginal size? I held off posting on this until Id come back from my gyno and could ask her. She said that there was nothing at all to indicate an increase in vaginal size. While the average person is becoming larger their sex organs are not increasing because there is no need for them to increase. She also suggested that, on the evidence of there being an 'average' size, a large penis could be deemed a recessive trait. As there is more mixing of cultures, clans, races, families etc there could be a reduction in the number of instances of men possessing larger than average dicks. When people married within the confines of those groups the trait was passed along so it gave the appearance that some groups were larger than others and was the cause of much myth making.

Interesting perspective I thought.

Not really, LeahCat. It might affect the size of the clitoris, the actual homologue of the vagina, but only if the change is activated by a hormone which occurs in roughly equal amounts in both sexes. The vagina masculina is the homologue of the vagina; it's functionlessly attached to the bladder.

that is so ridiculous it's not even worth commenting on.

precisely.

unfortuantely it seems like most people in this community need to get over their "bigger is better" mentality. i'm stunned that anyone would actually argue that having a larger than average penis is a "benefit" in terms of procreation. get over yourselves.

btw as for people not discussing vaginal growth over time, women don't consider the size of their vaginas to be among their most important defining characteristics so the subject would be less likely to come up. you won't be seeing women with large vaginas arguing that large vaginas make them "superior" from an evolutionary standpoint, but does it surprise anyone that men who claim to be above average in penis size are doing just that?

What I meant by sexual selection was different than ChimeraTX's idea. Basically sexual selection comes in two varieties:

Intrasexual -- I fight with you. I win. I get the females.
Intersexual -- I'm prettier than you. The females choose me. I get the females.

Intrasexual selection has a sub-type called sperm selection. Basically, sperm selection occurs when a female mates with multiple males; anything to hinder other males' sperm or help one's own sperm along in the race to the ovum is good here.

Essentially, sexual selection occurs because the female side of mating is always more expensive, biologically speaking, than the male side. Well, almost always; I'd say a male mantis has it harder than a female.

We shouldn't forget that if we're talking about modern evolution we have to consider how things happen now, rather than in caveman days. Does penis size influence the number of children a man has now? The answer may be different in different cultures and nations. Certainly the situation will be different where a lot of males are unable to marry (China in the future?), than in cultures where nearly all men find a mate.

Getting back to the topic about teenagers having "huge penises", I just don't think it's true from my own very scientific study!! :D I live in a dorm with hundreds of male late teen (18 & 19) students all of whom have penises (I believe this to be true). And I've seen many of those said penises on many occasions, and most of them are just "family sized". On occasion I've noticed some very large specimens, but those are just the show-offs trying to distract their peers from their reading. So according to my study this question has a flawed premise!

I agree with spermboy. I see the dicks of my peers often and they are mostly average (because that's what average is). There are of course some large ones and some small ones. I dont think the variation has changed at all.

I haven't read the study which found people on the whole "prefer" larger penises. I've gotten the impression people select those with whom they wish to procreate based on other characteristics.

ChimeraTX, I see that you have a point to make, but you haven't given any actual proof. it seems like you keep saying "people prefer larger penises, that means they're procreatively superior". other than conjecture, what makes you believe this?

I think it makes sense that, if the average height of adult males is increasing (is it?) then the average penis size would increase proportionally. That said, if the average penis is 6 inches and the average male is 5' 10" then an increase to 6" would result in only an 1/8" increase.

The idea of sexual selection doesn't really seem to make much sense. There don't seem to be a lot of men out there who desparately want to get married and have kids but remain single for their whole lives. And if there were, does anyone think they really all have tiny penises? And don't forget single guys father children all the time. And when a couple is trying to figure out whether to have children and, if so, how many, i doubt the size of the man's penis is really part of the equation.

One possibility is if married women are more likely to have an affair with a guy with a large penis and consequently some of the children of the marriage are in fact his.

I really do think penis size in teens is growing as is height. last year in high school I got the chance to see a lot of the guys in the locker room and I noticed everyone seemed hung like rhinos (flaccid), it was pretty interesting. I also noticed some freshman that we're extremely well hung, I hope they enjoy it, hahaha. the penis stops growing at like 17 or 18 so some of these kids are going to get bigger, which is incredibly large. the biggest ones I saw in high school were: 6", 11", 7", several 8 inchers, several 9 inchers and one 10" all flaccid. I guess I just went to an extremely well hung school....I guess thats why the girls always wanted inside our locker room, hahaha.

What are you talking about buddy? A longer penis increases the chance of successful impregnation during intercourse. Why are you stunned? It is simple attraction, on the mean, women prefer larger penises. Therefore, a larger penis would be a "benefit" is procreation.

Why do people get so hung-up on superiority? If a larger penis is a benefit in procreation, it is superior to a smaller one. I don't understand the problem. Do you not think what you are saying stems from your own biases, I mean seriously? Why wouldn't a larger penis be a benefit, as we can see the majority of people(chicos y chicas) prefer them?

LeahCat, why would other sexual traits(dimorphism) diminish and not the size of the penis? You seem to think it has no need to increase, so prove it. Larger vaginas would only be selected for if penis length begins to, on the mean, become too large, on the mean, for the average vagina.
[post=290953]Quoted post[/post]​

Well I hate to burst your bubble ChimeraTX, but a longer penis does not increase chances of getting pregnant. It depends on the sperm count of the man and how strong his swimmers are as well as how aroused the woman is during intercourse.

If the woman is sufficiently aroused and the long penis is shooting very few swimmers that are really slow then the chance of pregnancy is slim. Now if you have an average size penis with the woman being highly aroused and the man is shooting very active swimmers in a large quantity, then the chances are very high that pregnancy will occur.
