5 Truths About Average Penis Size For 15 Year Old

When they hit puberty, most boys and girls are curious and like to explore their bodies. To help you out, We enlisted five truths about average penis size for 15 years old.

  1. Your penis is only beginning to grow from here

At the age of 15, most boys are only beginning to hit their puberty, this means the penis will only be growing from this point onwards.

As such, it is understandable that not many boys will have a full-grown adult size penis.

Typically, it is only when a boy has reached the age of 16 that his penis size will be the same size of his adult penis size.

Even then, in reality some boys will either start their puberty a little earlier or later, so although there can be a general idea, every boy will experience different growth rate of the size of his penis and testicles.

Oh, and keep in mind that we are talking only about their flaccid penis state, not the state of an erect penis that would be a different story as every man's erections are affected by a lot more factors than just growth.

  1. The average penis size for a teenager is really not as big as you think

Thanks to free, but toxic learning material about sexuality that is called porn, a lot of young boys 'who consume such materials' may be under the impression that an adult man's penis size is really, really huge.

And so they begin to unrealistically expect the same for themselves.

While in reality, many porn actors are just especially endowed men who have been selected to be fit for the purposes of the porn industry.

It would not be an exaggeration to say that such people are the 'special ones?, and you surely don't need to be a 'special one? to feel like you matter at all.

In reality, multiple researches have observed that the average teen’s penis size is ‘normally’ at some 3 and a half inches when flaccid, and some 6 and a half inches when erect.

According to information provided by Healthline, the average flaccid (non-erect) length of a penis for many individuals at the age of 15 is approximately 3.75 inches. However, when erect, the average length typically falls within the range of 5 to 7 inches. In terms of girth or circumference, the average flaccid penis measures around 3.6 inches, while the average erect penis has a girth of approximately 4.5 inches. It's important to note that these measurements can vary among individuals.

  1. Uncircumcised penis may look bigger, but…

The debate for the differences in circumcised and uncircumcised penises seems to not have an end, even though many experts have tried their best to show that that there really is not that much difference in the two.

But then, in reality, many kinds of differences actually do exist between the two, and one of them is the appearance of a man's penis size based on whether or not he has been circumcised.

As it turns out, an uncircumcised penis does appear slightly bigger than their circumcised counterpart, but the twist is this only applies when the penis is flaccid.

This is all due to the extra flap of skin that is still protecting the tip of the penis.

But, once the uncircumcised man has an erection, that extra skin will be stretched back anyway, so there is really not that significant difference when both types of man are having an erection.

  1. Extra-small penis may be caused by Klinefelter syndrome

If you are at the age where you think your penis should have been a lot bigger by your age, or if you have noticed how your other peers are sporting a bigger endowment than you, there is a chance that you may have the Klinefelter syndrome.

The Klinefelter syndrome is when a boy foetus receives an extra X-chromosome which then makes their body develop more feminine features in comparison to the average boys.

According to MedlinePlus, individuals affected by this condition may experience additional symptoms, such as variations in their genitalia. These can include undescended testes, a urethral opening located on the underside of the penis, or a notably small-sized penis. It is worth noting that the testicles typically remain small in almost all men, and in some cases, the penis may not reach its adult size.

As a result of this syndrome, the boy will usually not fully develop his penis and testicles.

When such a condition has been found in a boy, the treatment usually involves a testosterone therapy to help jolt the production of the male hormones for the purpose of the boy’s physical growth.

However, if you are already past this age and your penis can’t grow anymore, just remember that what determines a man’s masculinity is not just the penis size.

  1. You can still grow at the age of 18, even 22

Are you worried that you might not be growing as normally as your peers? Don't be jumping to the fear wagon first, you may be what they call the late bloomers.

It is normal that some boys will begin puberty at a later age than their peers'the same is also true that some boys may begin a little earlier, too.

If you feel that at the age of 15 you are not yet growing, make a doctor's visit to see if you are simply growing later' there is nothing wrong about growing later either.

If this is your case, you can expect to grow more rapidly at the age or 18, in fact, some boys can still grow at the ages of 21 and 22, and this includes their penis, too.

According to Health Magazine, penis growth commences during puberty. This period is characterized by an increase in both the length and girth of the penis. On average, puberty begins around the age of 12 in males, and the growth process continues until the end of puberty, which typically occurs between the ages of 18 and 21.

If everything else about you is growing normally and you are not sick or anything, don’t worry too much and you can just wait for your time to come.

Bonus Tips Submitted By Viewers

  1. Experience involuntary erections and ejaculation

During puberty, you may have numerous erections for no apparent reason. Maybe your growing penis and excess testosterone are the causes.

The increased T cells trigger erection to occur after the slightest sexual hint or mere imagination. There is, unfortunately, nothing you can do to stop it. Eventually, though, the frequency and intensity of these erections reduce.

Most teens experience morning erection. This is perfectly normal and occurs four to five times at night.

This phenomenon has been extensively studied, and experts even have a name for it. It’s called nocturnal penile tumescence and happens during the REM state of sleep.

This involuntary erection is your body’s way of checking that all the penile veins are functioning well.

When your organs are at rest during sleep, there are increased activities along your penile parasympathetic system. It’s all about the natural stimulation of your nervous system.

Another issue that affects most teens is wet dreams. Here, you ejaculate during your sleep, either due to erotic dreams or for no reason.

  1. Shower vs grower

As a teen, you may notice that your flaccid penis size and that of your colleague vary significantly.

The size variation is what results in locker room harassment. Some boys think that they are massively endowed and so they torment their friends with small willys.

What they don’t seem to appreciate is that the two sets of penises are slight when both are erect. The massive shrinkage at the flaccid level is due to shower and grower effects.

The shower is a penis that appears big most of the time, even when not erect. In the shower a minute size change between their flaccid and fully erect stages.

Growers are those penises that are small when flaccid and grow massively when erect. Research findings showed that 79% of men have grower penises while 21% are showers.

Another study done in 2018 and published in IJIR journal established that growers' penises increased by 2.1 inches while showers increased marginally by 1.2 inches from these two states.

Tissue elasticity, overall teenage health, and collagen create the difference between these two penises' appearance.
